Perhaps you should try some spelling variations:
"by computational using simplex program" » "by computation using simplex program" (Expand search), "by computations using simplex program" (Expand search), "by computacional usinas simplex program" (Expand search), "_ computational using simplex program" (Expand search), "and computational using simplex program" (Expand search), "by computational using simples program" (Expand search), "by computational using complex program" (Expand search), "by computational using simple program" (Expand search), "by computational using samples program" (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: "((\"by computational using simplex program\") OR (\"using codigo python python programming\"))~".
• Removing quotes may allow a broader search: (( by computational using simplex program ) OR ( using codigo python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("by computational using simplex program") OR ("using codigo python python programming"))*.
