Perhaps you should try some spelling variations:
"_ computations using linear program" » "_ computation using linear program" (Expand search), "_ populations using linear program" (Expand search), "_ computations in linear program" (Expand search), "_ computations using linear programmin" (Expand search), "_ computations using linear programming" (Expand search)
"using codigo python python programming" » "using codigo pythons python programming" (Expand search), "using codigo piton python programming" (Expand search), "using codigo pitons python programming" (Expand search), "using indigo python python programming" (Expand search), "using coding python python programming" (Expand search), "using codium python python programming" (Expand search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("_ computations using linear program") OR ("using codigo python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"_ computations using linear program\") OR (\"using codigo python python programming\"))".
• Removing quotes may allow a broader search: (( _ computations using linear program ) OR ( using codigo python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("_ computations using linear program") OR ("using codigo python python programming"))*.
