[math] CMAESOptimizer fails sometimes when bounds are violated

2014-02-28 Thread Bruce Johnson
The CMAESOptimizer repairs points that are out of bounds by moving them into bounds, and adding a penalty based on how far they were moved. The penalty added is scaled by the range of values in the current population (valueRange field in code below). double[] x, final double[] repaired) {
