Perhaps you should try some spelling variations:
"advanced computation in nonlinear programming" » "advanced computation in linear programming" (Expand search), "advanced computations in nonlinear programming" (Expand search), "advanced computational in nonlinear programming" (Expand search), "advance computational in nonlinear programming" (Expand search), "advanced computation and nonlinear programming" (Expand search), "advanced computation of nonlinear programming" (Expand search), "advanced imputation in nonlinear programming" (Expand search), "advanced computation _ 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.

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