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)
"testing to python python programming" » "testing to pythons python programming" (Expand search), "testing to piton python programming" (Expand search), "testing to pitons python programming" (Expand search), "testing the python python programming" (Expand search), "testing _ python python programming" (Expand search), "testing 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 simplex program\") OR (\"testing to python python programming\"))~".
• Removing quotes may allow a broader search: (( based computation using simplex program ) OR ( testing to python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computation using simplex program") OR ("testing to python python programming"))*.
