################################################################################ Current dependencies: - src/main: - Java 5+ - src/test: - Java 5+ - JUnit 3.8.1 ################################################################################ Jafaran x.x, xxxx/xx/xx Changes since version 1.1 : - Comment correction. ################################################################################ Jafaran 1.1, 2015/12/13 Changes since version 1.0 : - Using a more standard layout for files. - Added SyncRNG, which adds synchronization on top of a RNG, and MTSyncRNG which makes use of it, and is apparently faster than MTConcRNG. "Sync" is now a new keyword, that identifies implementations that are thread-safe and blocking through synchronization. - Optimized MTConcRNG.nextLong(), by removing the loop, and moving temperings after CASes (less time spent between CASes, so less chance of failed CAS). ################################################################################ Jafaran 1.0, 2014/04/27 - License: Apache License V2.0. - Requires Java 1.5 or later. - Jafaran (Java Fast Random) provides fast, and for some more random, implementations of java.util.Random, with additional nextXXX() methods, and methods to retrieve and restore state. - The names of implementations contain "Conc" (for concurrent) if they are thread-safe and non-blocking, or "Seq" (for sequential) if they are not thread-safe. - Also provides an implementation of Ziggurat algorithm (based on J. A. Doornik paper, 2005), used by nextGaussian() methods of the provided implementations. - Principal classes: - Implementations using Mersenne-Twister algorithm (good pseudo-randomness): - MTConcRNG - MTSeqRNG - Implementations using Marsaglia Xor-Shift (fast): - MXSIntSeqRNG (32 bits) - MXSLongSeqRNG (64 bits) (nextLong() faster, larger period) - RandomConcRNG: Pseudo-RNG using the same algorithm than Random. - RandomRNGAdapter: Pseudo-RNG backed by a Random instance. - Ziggurat: Random-based implementation of Ziggurat algorithm. ################################################################################
