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 in python python programming" » "using in pythons python programming" (Expand search), "using in piton python programming" (Expand search), "using in pitons python programming" (Expand search), "using _ 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 in python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computation using nonlinear programming\") OR (\"using in python python programming\"))".
• Removing quotes may allow a broader search: (( based computation using nonlinear programming ) OR ( using in python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("based computation using nonlinear programming") OR ("using in python python programming"))*.
