The overview table should list some important properties I find myself comparing when selecting a sort algo: (a) stack usage, (b) heap usage, (c) whether the algo is stable.<p>E.g., I am a big fan of heap sort, because the implementation is very simple, and non-recursive (O(1) stack), uses no heap, and has worst-case time O(log n). It is almost perfect, but it is not stable. Now, mergesort fixes that stability issue (and its implementation is usually also very simple), but is often recursive (like this implementation) and it usually requires 'malloc()', because it cannot easily be run in-place. In an overview list, this dilemma would be nicely visible.
