WebInsertion Algorithms (Rosenkrantz, Stearns, Lewis, 1974) An insertion procedure takes a sub-tour on k nodes at iteration k and determines which of the remaining n-k nodes shall be inserted to the sub-tour next (the selection step) and where (between which two nodes) it should be inserted (the insertion step). Nearest Insertion. Step 1.
