Perhaps you should try some spelling variations:
"using computation in variational program" » "using computation in variational problem" (Expand search), "using computation in variational problems" (Expand search), "using computation in adaptational program" (Expand search), "using computational in variational program" (Expand search), "using imputation in variational program" (Expand search), "using compilation in variational program" (Expand search), "using computation and variational program" (Expand search), "using computation of variational program" (Expand search), "using computation on variational program" (Expand search), "using computation via variational program" (Expand search)
"using python python python programming" » "using pythons python python programming" (Expand search), "using piton python python programming" (Expand search), "using pitons python python programming" (Expand search), "usando python python python programming" (Expand search), "in python 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: "((\"using computation in variational program\") OR (\"using python python python programming\"))~".
• Removing quotes may allow a broader search: (( using computation in variational program ) OR ( using python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computation in variational program") OR ("using python python python programming"))*.
