| class ReverseEngine( OrderEngine ) | Source |
|---|
The ReverseEngine tries to reverse a selection of the parameters in place.
Input order : [0,1,2,3,4,5,6,7,8,9]
output order: [7,6,5,4,8,9,0,1,2,3]
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
