Configurable lru_cache #1

Closed duubi closed 1 year ago

duubi commented 1 year ago

Hello, the lru_cache (currently @lru_cache(maxsize=4096)) should be configurable. E.g. with 500 size/weight elements and capacity of 70000, the solution wasn't found on an actual Intel 3,2 GHz CPU even after more than 20 hours. After modification @lru_cache(maxsize=4096*4096) was introduced, the solution was found within 1 minute, consuming approx 7GB of RAM.
