Crossover and mutation impact

[giuliocorradini]

The impact of a crossover is not clear. Crossovers should move the candidate solution farther in space, while a single mutation should help exploring the neighbourhood. This translates in crossover generating solution that have a higher Hamming distance than those generated by single mutations, but whenever part of the rod changes, all the pieces after change with it.

Should we move to a first degree spline representation to reduce the effect of a mutation on the solution?
