Perhaps you should try some spelling variations:
"based computational using linear programmin" » "and computational using linear programmin" (Expand search), "by computational using linear programmin" (Expand search), "based computation using linear programmin" (Expand search), "based computations using linear programmin" (Expand search), "based computacional usinas linear programmin" (Expand search), "based computational using linear programming" (Expand search), "based computational using nonlinear programming" (Expand search)
"using codigo python python programming" » "using codigo pythons python programming" (Expand search), "using codigo piton python programming" (Expand search), "using codigo pitons python programming" (Expand search), "using indigo python python programming" (Expand search), "using coding python python programming" (Expand search), "using codium 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 computational using linear programmin\") OR (\"using codigo python python programming\"))~".
• Removing quotes may allow a broader search: (( based computational using linear programmin ) OR ( using codigo python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computational using linear programmin") OR ("using codigo python python programming"))*.
