Talk:Heap's algorithm

This article needs to be enhanced. It looks like this algorithm is a good solution to the problem. It is quite nice that it is short and works, and in 1963 it was most important to reduce complexity and memory consumption. But if you look what it does (the picture is very helpful with that) it is quite weird and does lots of unnecessary swaps. So, the pro and contra should be mentioned, and other algorithms like Steinhaus–Johnson–Trotter algorithm should be mentioned. 5.146.194.61 (talk) 14:53, 8 October 2014 (UTC)
