M.Sc. Thesis:

My M.Sc. thesis deals with heuristic reductions from knapsack problem to the problem of finding short vectors in integer lattices. The latter is efficiently solved by the Lenstra, Lenstra and Lovasz algorithm. A good reduction results in better ways of solving knapsack. Look at the short summary (ps, pdf) (better written), or full thesis (ps) (a bit messier).
