ktims	13f61e3a2b	part2: works up to the 4th iteration, then returns too high values ... I think the issue is not testing both possible paths for direction keypads, but doing this naively blows up the compute complexity (and I got the wrong answer)	2024-12-21 02:48:39 -08:00

ktims	b588837624	day18: small optimization - avoid duplicates ... not sure if the input contains dupes, but avoid doing a second path search if the square already contains a byte, seems like a small performance gain	2024-12-18 00:41:28 -08:00

ktims	2729799fa2	day18: optimize ... * Implement generic path tracing, so part 1 doesn't store and return the full path, just the count. * Improve part2 impl to only run path search if the block fell on our last path. * Start part2 path search from the best path position immediately before the placed block.	2024-12-17 23:51:09 -08:00

ktims	20e6889572	day16: improve perf again by going to i16 positions ... map dimensions fit in i16, so use those in data structures make grid support generic position type as long as they implement to i64	2024-12-16 01:06:39 -08:00
ktims	755fbbc53d	day16: refactor, optimize ... split path recording and best cost functions for big gainz use i32 instead of i64 positions to shrink data structures for some gainz	2024-12-16 00:58:15 -08:00
