Perhaps you should try some spelling variations:
"based computation using nonlinear programming" » "based computation using linear programming" (Expand search), "based computational using nonlinear programming" (Expand search), "based competition using nonlinear programming" (Expand search), "based compilation using nonlinear programming" (Expand search), "based computations using nonlinear programming" (Expand search), "based computation in nonlinear programming" (Expand search), "based composition 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.

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