Perhaps you should try some spelling variations:
"by computation in linear programming" » "by computational in linear programming" (Expand search), "of computation in linear programming" (Expand search), "_ computation in linear programming" (Expand search), "by computation and linear programming" (Expand search), "by computation of linear programming" (Expand search), "by imputation in linear programming" (Expand search), "by computation non linear programming" (Expand search), "by computation in line programming" (Expand search)
"using model python python programming" » "using model pythons python programming" (Expand search), "using model piton python programming" (Expand search), "using model pitons python programming" (Expand search), "using modulo python python programming" (Expand search), "using monty python python programming" (Expand search), "using tool python python programming" (Expand search), "ising model python python programming" (Expand search), "using modis python python programming" (Expand search), "using mobile 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: (("by computation in linear programming") OR ("using model python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"by computation in linear programming\") OR (\"using model python python programming\"))".
• Removing quotes may allow a broader search: (( by computation in linear programming ) OR ( using model python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("by computation in linear programming") OR ("using model python python programming"))*.
