WebNov 12, 2011 · I'm trying to implement an efficient hash table where collisions are solved using linear probing with step. This function has to be as efficient as possible. No needless = or == operations. My code is working, but not efficient. This efficiency is evaluated by an internal company system. It needs to be better. WebChaining remains a popular and performant approach to collision resolution, but linear probing has seen a resurgence in popularity. Techniques like “Robin Hood hashing” reduce the number of probes necessary to find keys contained within the table, and keeping the probe sequence close to the original index provides good memory locality ...
