Bug in Powell's Method: Limited angle when changing direction #51

Open SimonBlanke opened 3 months ago

SimonBlanke commented 3 months ago

In its current implementation of Powell's Method the change in direction does only happen orthogonally (or 90°) to the previous direction. To work properly it should allow a continuous range of angles.
