XorShiftAddSharp

This is a pure C# implementation of a XORSHIFT-ADD (XSadd) pseudo-random number generator.

Concept

• Small internal state size (128bit)
• Long period(2^128-1)
• Save and restore internal state anytime.
• Can Retrieve the arbitrary n-step jumped state.

Overview

• There is the implementation of almost same semantics of "xsadd.c" and "xsadd.h". (XorShiftAddCore)
• There is the implementation of Inherited by System.Random. (XorShiftAdd)
• Xml documentations are available (but currently partially)
• Compared tests from original library are passed.

Change Log

ver0.1

Initial release.

ver 0.2

Changed XorShiftAdd psesudo-random generator's internal state from Span<uint> to InternalState struct. Unfortunately this is a devastating changes from ver 0.1 .

ver 0.2.1

Fix: XorShiftAddCore and XorShiftAdd class Jump method's baseStep parameter can now be prefixed with "0x" or "0X". (Previous Jump method could be accept prefix, but CalculateJumpPolynomial couldn't be accept prefix.)

ver 0.3.0.0

Add XorShiftAddPool XorShiftAddPoolObjectPolicy

These are provides the object pool. That are outputs are 2^64 range splitted instance.

Ver1.0.0.0

Add xml comment to XorShiftAddCore.cs Fixed incorrect test fixture.

Ver1.0.1.0

Trivial fix.
