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

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