eu.planets_project.pp.plato.sensitivity.SimpleIterativeWeightModifier
This weight modifier sees the weights as n-dimensional space. E.g. if you have a node with three children A, B, C it interprets the their weights as three dimensional space where the values in each dimension can be 0 <= w <= 1. Each dimension (=each weight) gets values from (original_value - LIMIT) to (original_value + LIMIT) in STEPS steps. Example: let's assume A has the weight 0.35, LIMIT = 0.05 and STEPS = 3. Then A will get the following weights: 0.30, 0.35 and 0.40. Of course this is done to B and C as well. In total there is STEPS^n combinations - the number of iterations grows exponentially with the number of nodes. @author Jan Zarnikov
