More precisely, at four freecells I'm working with 125 weights for the
quickest solution (fails to solve 1 of 200000 deals), 151 weights for the
sure solution, and about 20 blocks/prunes. Currently my utility program that
finds the quickest attack fails for unknown reasons. Gdb is no help; with -O0
it tells me it fails at a place in the listing between functions. (I run
screaming from the room...)
