WARNING FIX - remove sscanf in favor of strtoul or strtoull or _strtoui64 for set.generator(). - remove sprintf in favor of a dedicated ulltostr for get.description(). Version 2.0.3 ============= - re-enable the use of set.generator(name="congruRand",...). - remove almost all URL and/or replace by DOI or text. WARNING FIX - remove the following warning in some C functions: a function declaration without a prototype is deprecated in all versions of C [-Wstrict-prototypes] BUG FIX - correct the dimnames of sobol() outputs, reported by Arnald Puy. Version 2.0.2 ============= NOTE FIX - remove an escaped LaTeX special in pseudoRNG.Rd. - remove math rendering problems for Stirling numbers in colltest.Rd and colltestsparse.Rd. Version 2.0.1 ============= BUG FIX - two errors appearing in USBAN memory tests. Previous output when re-building fullpres.Rnw was LowDiscrepancy-sobol-orig1111.c:1418:32: runtime error: left shift of 1 by 31 places cannot be represented in type 'int' LowDiscrepancy-sobol-orig1111.c:1440:57: runtime error: left shift of 1 by 31 places cannot be represented in type 'int' Version 2.0.0 ============= - remove Fortran code for Halton and Sobol sequences (the latter was under the ACM licence). - scrambling for Sobol sequences is temporarily disabled: the Fortran version of Sobol sequences can be found on R-forge in randsobolfortran package. Version 1.31.2 ============= - last version with both Fortran and C code (never released on CRAN). Version 1.31.1 ============= BUG FIX - clean up test files because tests/test-sobol-scram.R failed on i386-pc-solaris2.10 (32-bit). Output was > umat <- sobol(n=1e5, dim=1111) Error: cannot allocate vector of size 423.8 Mb Version 1.31.0 ============= NEW FEATURES - add new test files. - increase argument checks in QRNG. - allows to start QRNG from 0, see https://arxiv.org/abs/2008.08051 by Art Owen, a warning is not raised when start != 0. - update vignettes. WARNING FIXES - fix warnings of autoconf for configure files showed by > autoreconf --warnings=obsolete (previous output was) configure.ac:310: warning: The macro `AC_TRY_COMPILE' is obsolete. configure.ac:310: warning: The macro `AC_TRY_RUN' is obsolete. configure.ac:310: warning: The macro `AC_FD_MSG' is obsolete. configure.ac:321: warning: The macro `AC_CONFIG_HEADER' is obsolete. - fix invalid URLs (from http to https) BUG FIX - correctly generate a seed for Sobol mixed sequences. Version 1.30.1 ============= - update the man page for quasi random sequences. - allow the use of randomized seed for Sobol sequences (either from scrambling argument or mixed argument). BUGS FIX - bug fixes on array limit issues in Fortran code (in INITSOBOL). - warning fix on unused variable in Fortran code (in SGENSCRMU). - bug fixes on multiple defintion issues (for WELL_get_set_entry_point, WELLrng, setSeed4WELL) in C header files, thanks to Brian Ripley. - scrambling = 1, 3 for Sobol sequences may generate 0.0, so randomizing the seed is performed in that case. Version 1.30.0 ============= - disable the use of set.generator(name="congruRand",...). - clean up C code. Version 1.20 (never released on CRAN) ============= - translate Fortran code of Diethelm Wuertz for Halton sequence into C. - by default halton() use the C code slightly faster than the Fortran code. - start to translate Fortran code of Diethelm Wuertz for Sobol sequence into C. - add defensive programming for QMC. BUGS FIX - scrambling = 1, 3 for Sobol sequences (provided by Makoto Matsumoto and Mutsuo Saito). - mixed = TRUE for QMC sequences. - correct use of 64-bit integer type - correct failures in if statements (length > 1 in coercion to logical) in quasiRNG.R and pseudoRNG.R NOTE FIX - usage of R_useDynamicSymbols to preclude compilation NOTEs, better registration of native routines and reduced symbol visibility. Versions 1.17 and 1.17.1 ============= - change DESCRIPTION file. - update NAMESPACE for R 3.3.0. - update the LICENSE file. - raise a warning when scrambling for Sobol sequences is incorrect. BUG REPORT (by Dan Souther, Kemal Dincer Dingec, Marius Hofert, Nicolas Chopin, Andrei Kostyrka) - scrambling = 1, 3 for Sobol sequences. (by Hiroyuki Kawakatsu) - mixed = TRUE for QMC sequences.

NOTES FIXES - this version use packageStartupMessage function for the .onAttach rather than the cat function. - remove a printf in KnuthTAOCP2002.c WARNING FIXES in C files - remove warnings with Wall and pedantic gcc options. For this purpose, files randtoolbox/src/Makevars and rngWELL/src/Makevars now contain a line, uncommenting which includes Wall and pedantic. See https://stat.ethz.ch/pipermail/r-sig-mac/2008-August/005251.html BUG FIX - the package crashes when the dimension was 0 in RNG functions, reported by David LeBauer.

WARNING FIXES - fix some warnings following the release of R 2.13.0: the Makefile and the man page of runifInterface. - fix a warning in the MT19937 file. BUG FIX - remove implicit type declaration in the LowDiscrepancy fortran file, which causes errors with GCC 4.6 compilers. Version 1.09 ============= NEW FEATURES - start runif interface for congruential generator and WELL RNG, - vignette contains two chapters, - start to test true randomness (not included in this version), - increase the speed and accuracy of Halton and Sobol sequences. STRUCTURAL CHANGE - Before version 1.09, there was a lot of different (and incompatible) licences in this package, namely, GPL, BSD, public domain, etc... (cf. 1.08-version DESCRIPTION file of this package). - From 1.09, all this code of this package is under the new BSD licence. A copy of the BSD licence is available at https://opensource.org/licenses/bsd-license.php - extract Pierre L'Ecuyer's code from randtoolbox and put it in a dedicated package rngWELL, - depends now on rngWELL. AUTHORS - all the code of this package except the ones listed below was written by Yohan Chalabi, Christophe Dutang, Petr Savicky and Diethelm Wuertz. - the code for SF-Mersenne Twister belongs to M. Matsumoto and M. Saito, which is under the new BSD licence. - the code for Knuth-TAOCP-2002 generator belongs to D. E. Knuth. This code is in the public domain and freely copyable. BUG FIX - normal transformation of Halton and Sobol sequences is correct. BUG REPORT - Halton and Sobol sequences did not work on 64bit architecture when using normal transformation reported by Anirban Mukherjee, - Sobol sequences for dimension > 2 need to be tested. Version 1.08 (never released on CRAN) ============= NEW FEATURES - add function get.primes, - table of primes moved from randtoolbox.c to primes.h and compressed by storing half difference from the previous prime instead of each prime (except for 2 and 3), - start runifinterface. Version 1.07 ============= NEW FEATURES - integrate code for Halton, Sobol sequence from fBasics (Rmetrics), - randoolbox is now part of Rmetrics project (available on R-forge), - increase the speed of congruRand. BUG FIXES - fix setSeed function, - a warning shows up on 64 bit architecture. BUG REPORT - setting the seed with WELL's RNGs was not correct, reported by Petr Savicky. Version 1.06 ============= BUG FIX - the degree of freedom is now correct for the order test. BUG REPORT - Astley Lin reports that the degree-of-freedom(df) of chi-square test is wrong for the order test. Version 1.05 ============= NEW FEATURES - add new WELL generators based on L'Ecuyer's code, - add the Sobol and Halton sequences from fOptions package. BUG FIX - it compiles on 64bit linux both on CRAN and R-forge. Version 1.04 ============= BUG REPORT - the package does not compil on Fedora 8 x86_64 boxes, reported by Brian Ripley. Version 1.03 ============= NEW FEATURES - add the WELL generator thanks to the code of P. L'Ecuyer, - SFMT now allows for different mersenne exponents as well as parameter sets, - increase the possible dimension for Torus algorithm from 1000 to 100 000, - add the RAN_ARRAY generator of Knuth TAOCP (2002), - the function setRandSeed has be renamed by setSeed, - update the vignette. Version 1.02 ============= NEW FEATURES - more random generation tests such as collision test and order test, - poker test is generalized to any dimension, - some auxiliary functions, - a detailed vignette on generating and testing random generation. BUG FIXES - on windows, when the seed was not fixed by the user, we use the machine time. But we use only seconds of machine time not micro second like on unix-like system. Hence a call like this > for(i in 1:10) print(congruRand(1)) produces the same output. Now it is fixed. Version 1.01 (never released on CRAN) ============= NEW FEATURES - add withtorus option for SFMT function, - improve output of tests. Version 1.00 ============= - Initial release based on the torus package (which is no longer available).
