Perhaps you should try some spelling variations:
"based computation and linear programming" » "based computational and linear programming" (Expand search), "based competition and linear programming" (Expand search), "based compilation and linear programming" (Expand search), "based computation of linear programming" (Expand search), "based computation and nonlinear programming" (Expand search)
"using modis python python programming" » "using modis pythons python programming" (Expand search), "using modis piton python programming" (Expand search), "using modis pitons python programming" (Expand search), "using codigos python python programming" (Expand search), "using codigo python python programming" (Expand search), "using modulo 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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computation and linear programming\") OR (\"using modis python python programming\"))~".
• Removing quotes may allow a broader search: (( based computation and linear programming ) OR ( using modis python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computation and linear programming") OR ("using modis python python programming"))*.
