SwitchEngine

 
SwitchEngine = class SwitchEngine(OrderEngine)
    SwitchEngine(walkers, errdis, copy=None, seed=4213, verbose=0)
 
The SwitchEngine tries exchange two parameters.
 
 
 
It belongs to the class of generalized travelling salesman problems
where the parameters of the problem is an ordered list.
 
The walker is kept when the logLikelihood > lowLhood
 
Author       Do Kester.
