Perhaps you should try some spelling variations:
"based computation using linear programming" » "based computational using linear programming" (Expand search), "based competition using linear programming" (Expand search), "based compilation using linear programming" (Expand search), "based computations using linear programming" (Expand search), "based computation in linear programming" (Expand search), "based composition using linear programming" (Expand search)
"using mass python python programming" » "using mass pythons python programming" (Expand search), "using mass piton python programming" (Expand search), "using mass pitons python programming" (Expand search), "using msn python python programming" (Expand search), "using dados python python programming" (Expand search), "using manim 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 using linear programming") OR ("using mass python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computation using linear programming\") OR (\"using mass python python programming\"))*".
• Removing quotes may allow a broader search: (( based computation using linear programming ) OR ( using mass python python programming ))*.
