Perhaps you should try some spelling variations:
"based computational using linear programming" » "and computational using linear programming" (Expand search), "by computational using linear programming" (Expand search), "based computation using linear programming" (Expand search), "based computations using linear programming" (Expand search), "based computacional usinas linear programming" (Expand search)
"using monty python python programming" » "using monty pythons python programming" (Expand search), "using monty piton python programming" (Expand search), "using monty pitons python programming" (Expand search), "using monte python python programming" (Expand search), "using many python python programming" (Expand search), "using mono python python programming" (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computational using linear programming\") OR (\"using monty python python programming\"))~".
• Removing quotes may allow a broader search: (( based computational using linear programming ) OR ( using monty python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computational using linear programming") OR ("using monty python python programming"))*.
