#2986 closed defect (done)

RoundedNormalAllPositionsManipulator applies bounds incorrectly

Reported by: jkarder Owned by: jkarder
Priority: medium Milestone: HeuristicLab 3.3.16
Component: Encodings.IntegerVectorEncoding Version: trunk
Keywords: Cc:


Since RoundFeasible was introduced, which takes care of transforming each dimension into a feasible value, part of the old transformation code was left over, which leads to wrong manipulations:

int value = (vector[i] + (int)Math.Round((N.NextDouble() * sigma[i % sigma.Length])) - min) / step; // transformation 1
max = FloorFeasible(min, max, step, max - 1);
vector[i] = RoundFeasible(min, max, step, value); // transformation 2

r16619: fixed value transformation in RoundedNormalAllPositionsManipulator

Do we need a version increment?

Reviewed r16619. Let's ignore a version increment, the integer vector encoding is currently hardly used.
