Overtested Release

Added

• Distribution Tests

Extreme Release

Added

• Extreme Value distribution.
• Inclusive float and double generation methods to XorShift engines.
• LCG32 and LCG64 random engines and their distribution wrappers.
• Xoroshiro128+ random engine ana its distribution wrapper.

Removed

• Long, Ulong and Double generation methods from XorShift32 random engine.

Fallback editor fix

Fixed

• DiscreteGeneratorProviderEditor is not Fallback now. It caused issues with some Custom Editors.

Restructure & new distributions

Added

• XorShift128 random engine and wrappers for it.
• Geometric distribution.
• Distributions with setup data (Gamma, Binomial, Geometric, Negative Binomial, Poisson, Weighted)
  got special methods and Setup structs that help to compute setup data once and reuse it.
• UnityGeneratorStruct. It's the same thing as UnityGeneratorClass but it's a struct.
  It's used in distributions to mimic IContinuousGenerator.
• FuncGeneratorClass and FuncGeneratorStruct. They are wrappers over Func. They are used
  to mimic IContinuousGenerator. The latter is used in distributions.
• AddModificator for continuous and discrete generators.
• MultiplyModificator for continuous generators.
• Weibull distribution.

Changed

• Unity 2019.4 is now required.
• XorShift algorithms can now jump forward.
• Generators and filters are not serializable anymore.
• UnityGenerator is renamed to UnityGeneratorClass.
• All distributions now use the same method for UnityEngine.Random, Func and IContinuousGenerator
  as iid sources.
• Exponential, Gamma, Bernoulli, Binomial, Geometric, Negative Binomial distributions now require
  iid sources in range [0, 1). All other distributions can work with iid sources in range [0, 1].

Removed

• UnityGeneratorSimple.
• All non-standard methods were removed from distributions. Those were methods that modified the result -
  use AddModificator or MultiplyModificator to get such a functionality. It affected Bates, Exponential,
  Gamma, Irwin-Hall, Binomial, Geometric, Negative Binomial and Poisson distributions.
• Simple generators of mentioned above distributions were removed. Now non-simple generators do the same.

XorShift32(64)

Added

• Exponential distribution.
• XorShift32 random engine and wrappers for it.
• XorShift64 random engine and wrappers for it.

Changed

• Distributions now use normal epsilon because
  some CPUs don't support standard C# denormal epsilon.

Fixed

• Binomial distribution became more correct.

Optimization, fixes & new distributions

Added

• DropSharedGenerator() and DropSharedFilter() methods. They allow to drop a current generator/filter and create a new one on a next call of sharedGenerator/sharedFilter property.
• Editable Weighted generator providers.
• Gamma distribution.
• Negative Binomial distribution.
• Weighted distribution editor.

Changed

• Marsaglia distribution is renamed to Normal distribution.
• Binomial distribution is rewritten and became much faster.
• Poisson distribution is rewritten to avoid infinite loops.
• Inlining of some methods is changed for performance reasons and more compact assemblies.

Removed

• Box-Muller distribution. If you use it, start to use Normal distribution.

Fixed

• NormalGenerator didn't use its parameters.

Long paths fix

Changed

• Project structure is changed to shorten paths to avoid long paths.
• AcceptanceRejection... names are renamed to Rejection... names.
• Namespace Zor.RandomGenerators.ContinuousDistributions.IndependentDistributions is shortened to Zor.RandomGenerators.ContinuousDistributions.
• Namespace Zor.RandomGenerators.ContinuousDistributions.NormalDistributions is shortened to Zor.RandomGenerators.ContinuousDistributions.
• Namespace Zor.RandomGenerators.ContinuousDistributions.UniformDistributions is shortened to namespace Zor.RandomGenerators.ContinuousDistributions.
