Perhaps you should try some spelling variations:
"based computation using simplex program" » "based computational using simplex program" (Expand search), "based competition using simplex program" (Expand search), "based compilation using simplex program" (Expand search), "based computations using simplex program" (Expand search), "based computation in simplex program" (Expand search), "based composition using simplex program" (Expand search), "based computation using simples program" (Expand search), "based computation using complex program" (Expand search), "based computation using simple program" (Expand search), "based computation using samples program" (Expand search)
"using modeling python python programming" » "using modeling vpython python programming" (Expand search), "using modeling pitting python programming" (Expand search), "using model python python programming" (Expand search), "using modern python python programming" (Expand search), "using models python python programming" (Expand search), "using modeling pythons python programming" (Expand search), "using modeling piton python programming" (Expand search), "using modeling pitons 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 simplex program\") OR (\"using modeling python python programming\"))~".
• Removing quotes may allow a broader search: (( based computation using simplex program ) OR ( using modeling python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computation using simplex program") OR ("using modeling python python programming"))*.
