#2797:

  • Updated PSO to make it more compatible with SPSO 2011
  • Removed truncation of velocity vector and instead rescaled it given the maximum velocity
  • Added non-zero initial velocity according to SPSO 2011
  • Removed complicated bouncing code due to box constraints and instead implemented as described in SPSO 2011
  • Calculating neighbor best has been changed to use personal best
  • Avoiding local and global particle update and instead relying on neighborbest
  • More randomization during velocity update by using a separate random numbers per dimension
  • Reusing problem specific solution creator in RealVectorParticleCreator instead of always using UniformRandomRealVectorCreator
