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