Integer overflow exception at absOptimization..ctor()

[Worldexe]

Namespace Optimization
    ...
    Public MustInherit Class absOptimization
        ...
        Protected m_rand As System.Random = New clsRandomXorshift(CUInt(Environment.TickCount))

Environment.TickCount can actually return negative number (it does at my machine).

There should be
Protected m_rand As System.Random = New clsRandomXorshift(BitConverter.ToUInt32(BitConverter.GetBytes(Environment.TickCount), 0))

Thank you for finding the bug. When a negative number is an argument, exception is raised.
I fixed absOptimization in your code.
