17 Oct 2014 Fuzzy Approximation This is a simple function approximation method I Author: Night KNight

Simple to understand.

09 Apr 2014 1+1 Evolution Strategy (ES) 1+1-ES. The simplest ES. Read comments in the file for a deeper explanation and bibliography Author: Gilberto A. Ortiz

Actually in the main file you are doing double size of required function evaluations. You can move the fx=f(xkm1); before the while loop. and add fx=fy; inside the if statement after xkm1=y;
this way you evaluate each function as it many times that it needs not more.

13 Sep 2014 Q-learning (Model-free Value Iteration) Algorithm for Deterministic Cleaning Robot An Example for Reinforcement Learning using Q-learning with epsilon-greedy exploration Author: Reza Ahmadzadeh Wei, Zhang

wonderful example to illustrate model-free value iteration. Looking for demos dealing with system with uncertainty. That will further shows this method's characteristics.

05 Sep 2014 Edit Distance Algorithm Edit Distance is a standard Dynamic Programming problem. Author: Reza Ahmadzadeh Richter, Jens

Simple and powerful :-)
