Perhaps you should try some spelling variations:
"based computational using nonlinear program" » "and computational using nonlinear program" (Expand search), "by computational using nonlinear program" (Expand search), "based computation using nonlinear program" (Expand search), "based computations using nonlinear program" (Expand search), "based computacional usinas nonlinear program" (Expand search), "based computational using nonlinear programing" (Expand search), "based computational using linear program" (Expand search), "based computational using nonlinear problem" (Expand search)
"using model python python programming" » "using model pythons python programming" (Expand search), "using model piton python programming" (Expand search), "using model pitons python programming" (Expand search), "using modulo python python programming" (Expand search), "using monty python python programming" (Expand search), "using tool python python programming" (Expand search), "ising model python python programming" (Expand search), "using modis 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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("based computational using nonlinear program") OR ("using model python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computational using nonlinear program\") OR (\"using model python python programming\"))*".
• Removing quotes may allow a broader search: (( based computational using nonlinear program ) OR ( using model python python programming ))*.
