Hi Ross:
I know you have been writing about search instability, are you also implementing
measures with Trace to make the search more stable? Trace's search with fine
#70 looks a lot more stable than Bruja's. When Trace finds Kb1 she sticks with
it. With Bruja (output below), Kb1 fails high with a +3 score at iteration 18.
It then promptly fails low. Bruja rattles around until iteration 26 before it
locks onto Kb1 with a steadily increasing score.
Best
