 Generate the k best solutions to a              
  knapsack problem. 
   For some problems there may be an obvious,
  easy to compute objective, but also less
  easily quantified considerations. Thus,
  we may want to look at the k best 
  solutions according to the quantified
  objective, and then manually choose
  the most attractive solution, taking into
  account the unquantified, multi-criteria considerations.
   If all the decision variables are 0/1,
  then generating the k best is easy to do;
