By contrast, our General Public -License is intended to guarantee your freedom to share and change free -software--to make sure the software is free for all its users. The -General Public License applies to the Free Software Foundation's -software and to any other program whose authors commit to using it. -You can use it for your programs, too. - - When we speak of free software, we are referring to freedom, not -price. Specifically, the General Public License is designed to make -sure that you have the freedom to give away or sell copies of free -software, that you receive source code or can get it if you want it, -that you can change the software or use pieces of it in new free -programs; and that you know you can do these things. - - To protect your rights, we need to make restrictions that forbid -anyone to deny you these rights or to ask you to surrender the rights. -These restrictions translate to certain responsibilities for you if you -distribute copies of the software, or if you modify it. - - For example, if you distribute copies of a such a program, whether -gratis or for a fee, you must give the recipients all the rights that -you have. You must make sure that they, too, receive or can get the -source code. And you must tell them their rights. - - We protect your rights with two steps: (1) copyright the software, and -(2) offer you this license which gives you legal permission to copy, -distribute and/or modify the software. - - Also, for each author's protection and ours, we want to make certain -that everyone understands that there is no warranty for this free -software. If the software is modified by someone else and passed on, we -want its recipients to know that what they have is not the original, so -that any problems introduced by others will not reflect on the original -authors' reputations. - - The precise terms and conditions for copying, distribution and -modification follow. - - GNU GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License Agreement applies to any program or other work which -contains a notice placed by the copyright holder saying it may be -distributed under the terms of this General Public License. The -"Program", below, refers to any such program or work, and a "work based -on the Program" means either the Program or any work containing the -Program or a portion of it, either verbatim or with modifications. Each -licensee is addressed as "you". - - 1. You may copy and distribute verbatim copies of the Program's source -code as you receive it, in any medium, provided that you conspicuously and -appropriately publish on each copy an appropriate copyright notice and -disclaimer of warranty; keep intact all the notices that refer to this -General Public License and to the absence of any warranty; and give any -other recipients of the Program a copy of this General Public License -along with the Program. You may charge a fee for the physical act of -transferring a copy. - - 2. You may modify your copy or copies of the Program or any portion of -it, and copy and distribute such modifications under the terms of Paragraph -1 above, provided that you also do the following: - - a) cause the modified files to carry prominent notices stating that - you changed the files and the date of any change; and - - b) cause the whole of any work that you distribute or publish, that - in whole or in part contains the Program or any part thereof, either - with or without modifications, to be licensed at no charge to all - third parties under the terms of this General Public License (except - that you may choose to grant warranty protection to some or all - third parties, at your option). - - c) If the modified program normally reads commands interactively when - run, you must cause it, when started running for such interactive use - in the simplest and most usual way, to print or display an - announcement including an appropriate copyright notice and a notice - that there is no warranty (or else, saying that you provide a - warranty) and that users may redistribute the program under these - conditions, and telling the user how to view a copy of this General - Public License. - - d) You may charge a fee for the physical act of transferring a - copy, and you may at your option offer warranty protection in - exchange for a fee. - -Mere aggregation of another independent work with the Program (or its -derivative) on a volume of a storage or distribution medium does not bring -the other work under the scope of these terms. - - 3. You may copy and distribute the Program (or a portion or derivative of -it, under Paragraph 2) in object code or executable form under the terms of -Paragraphs 1 and 2 above provided that you also do one of the following: - - a) accompany it with the complete corresponding machine-readable - source code, which must be distributed under the terms of - Paragraphs 1 and 2 above; or, - - b) accompany it with a written offer, valid for at least three - years, to give any third party free (except for a nominal charge - for the cost of distribution) a complete machine-readable copy of the - corresponding source code, to be distributed under the terms of - Paragraphs 1 and 2 above; or, - - c) accompany it with the information you received as to where the - corresponding source code may be obtained. (This alternative is - allowed only for noncommercial distribution and only if you - received the program in object code or executable form alone.) - -Source code for a work means the preferred form of the work for making -modifications to it. For an executable file, complete source code means -all the source code for all modules it contains; but, as a special -exception, it need not include source code for modules which are standard -libraries that accompany the operating system on which the executable -file runs, or for standard header files or definitions files that -accompany that operating system. - - 4. You may not copy, modify, sublicense, distribute or transfer the -Program except as expressly provided under this General Public License. -Any attempt otherwise to copy, modify, sublicense, distribute or transfer -the Program is void, and will automatically terminate your rights to use -the Program under this License. However, parties who have received -copies, or rights to use copies, from you under this General Public -License will not have their licenses terminated so long as such parties -remain in full compliance. - - 5. By copying, distributing or modifying the Program (or any work based -on the Program) you indicate your acceptance of this license to do so, -and all its terms and conditions. - - 6. Each time you redistribute the Program (or any work based on the -Program), the recipient automatically receives a license from the original -licensor to copy, distribute or modify the Program subject to these -terms and conditions. You may not impose any further restrictions on the -recipients' exercise of the rights granted herein. - - 7. The Free Software Foundation may publish revised and/or new versions -of the General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - -Each version is given a distinguishing version number. If the Program -specifies a version number of the license which applies to it and "any -later version", you have the option of following the terms and conditions -either of that version or of any later version published by the Free -Software Foundation. If the Program does not specify a version number of -the license, you may choose any version ever published by the Free Software -Foundation. - - 8. If you wish to incorporate parts of the Program into other free -programs whose distribution conditions are different, write to the author -to ask for permission. For software which is copyrighted by the Free -Software Foundation, write to the Free Software Foundation; we sometimes -make exceptions for this. Our decision will be guided by the two goals -of preserving the free status of all derivatives of our free software and -of promoting the sharing and reuse of software generally. - - NO WARRANTY - - 9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY -FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN -OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES -PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED -OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF -MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS -TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE -PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, -REPAIR OR CORRECTION. - - 10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR -REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, -INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING -OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED -TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY -YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER -PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE -POSSIBILITY OF SUCH DAMAGES. - - END OF TERMS AND CONDITIONS - - Appendix: How to Apply These Terms to Your New Programs - - If you develop a new program, and you want it to be of the greatest -possible use to humanity, the best way to achieve this is to make it -free software which everyone can redistribute and change under these -terms. - - To do so, attach the following notices to the program. It is safest to -attach them to the start of each source file to most effectively convey -the exclusion of warranty; and each file should have at least the -"copyright" line and a pointer to where the full notice is found. - - <one line to give the program's name and a brief idea of what it does.> - Copyright (C) 19yy <name of author> - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation; either version 1, or (at your option) - any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The advantage of an LCA is that it is -// perfectly uniform when run for the entire period -// length (and very uniform for smaller sequences -// too, if the parameters are chosen carefully). -// -// ACGs have extremly long period lengths and -// provide good independence. Unfortunately, -// uniformity isnt not too great. Furthermore, I -// didnt find any theoretically analysis of ACGs -// that addresses uniformity. -// -// The RNG given below will return numbers -// generated by an LCA that are permuted under -// control of a ACG. 2 permutations take place: the -// 4 bytes of one LCG generated number are -// subjected to one of 16 permutations selected by -// 4 bits of the ACG. The permutation a such that -// byte of the result may come from each byte of -// the LCG number. This effectively destroys the -// structure within a word. Finally, the sequence -// of such numbers is permuted within a range of -// 256 numbers. This greatly improves independence. -// -// -// Algorithm M as describes in Knuths "Art of Computer Programming", -// Vol 2. 1969 -// is used with a linear congruential generator (to get a good uniform -// distribution) that is permuted with a Fibonacci additive congruential -// generator to get good independence. -// -// Bit, byte, and word distributions were extensively tested and pass -// Chi-squared test near perfect scores (>7E8 numbers tested, Uniformity -// assumption holds with probability > 0.999) -// -// Run-up tests for on 7E8 numbers confirm independence with -// probability > 0.97. -// -// Plotting random points in 2d reveals no apparent structure. -// -// Autocorrelation on sequences of 5E5 numbers (A(i) = SUM X(n)*X(n-i), -// i=1..512) -// results in no obvious structure (A(i) ~ const). -// -// Except for speed and memory requirements, this generator outperforms -// random() for all tests.

We remove common factors of powers of 2 from relevant - * quantities. - * 5. When converting floating-point integers less than 1e16, - * we use floating-point arithmetic rather than resorting - * to multiple-precision integers. - * 6. When asked to produce fewer than 15 digits, we first try - * to get by with floating-point arithmetic; we resort to - * multiple-precision integer arithmetic only if we cannot - * guarantee that the floating-point calculation has given - * the correctly rounded result.
