WebDec 27, 2024 · 2-Opt is a local search tour improvement algorithm proposed by Croes in 1958 [3]. It originates from the idea that tours with edges that cross over aren’t optimal. 2-opt will consider every possible 2-edge swap, swapping 2 edges when it results in an improved tour. 2-Opt. 2-opt takes O (n^2) time per iteration.
