Hi, I played with Richs ant colony these days, and want to report about experience with 4 cores.
First I didn't want my computer to idle, so I set * (def dim 140) was 80 * (def food-places 13) was 35 - I hoped for more defined routes. In vain. * (def food-range 1000) was 100 to have enough. and the 3 sleep times to, well, zero. With only these changes the display was completely frozen and didn't unfroze even after an hour. I also got "Transaction failed after reaching retry limit" Exceptions. So I raised the value for :min-history as suggested by Rich. (def world .. (ref (struct cell 0 0) :min-history 2) ..) But 2 wasn't enough. Even with 5 the display wasnt good. I had to go up to until 7 to have an almost stable situation. When I looked at the ref-history-count after a while, a couple of the had rised to 8. So this value needed is almost in the range of reaching the default :max-history (the default is 10). This is what I want to share, maybe its of help to somebody. Kind regards, alux -- You received this message because you are subscribed to the Google Groups "Clojure" group.
