An excellent source of information, code, etc. with regards to metaheuristics

I actually spent some time working on a small simulation library during my MS degree called SimLib and I must say it is a quite interesting topic all the way from technical and implementation details to application!

Efficiency is King!

Formato. The most interesting aspect of CFO is that it is fully deterministic unlike PSO, GA, AIS, or any of the other PIS based techniques.

The papers that he has produced on the topic can be found at:

  1. Are Near Earth Objects the Key to Optimization Theory?
  2. Central Force Optimization: A New Metaheuristic with Applications in Applied Electromagnetics
  3. Central Force Optimization: A New Nature Inspired Computational Framework for Multidimensional Search and Optimization
  4. Central Force Optimization: A New Deterministic Gradient -like Optimization  Metaheuristic
  5. Comparative Results: Group Search Optimizer and Central Force Optimization
  6. Pseudorandomness in Central Force Optimization
  7. Central Force Optimization Applied to the PBM Suite of Antenna Benchmarks

All I wanted was some simple code for both Real and Binary PSO – but I couldn’t find anything I like! So, I’m providing a file containing both along with the RNG that I used. Please be aware that this code has not been refined. It’s clear, but rather ugly.
