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 total python python programming" » "using total pythons python programming" (Expand search), "using total piton python programming" (Expand search), "using total pitons python programming" (Expand search), "using tool 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 computation using linear programming\") OR (\"using total python python programming\"))~".
• Removing quotes may allow a broader search: (( based computation using linear programming ) OR ( using total python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computation using linear programming") OR ("using total python python programming"))*.
