Perhaps you should try some spelling variations:
"using computational and complexity program" » "and computational and complexity program" (Expand search), "using computational and complex program" (Expand search), "using computational and complexity from" (Expand search), "using computational and complexity priors" (Expand search), "using computational fluid complexity program" (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: (("using computational and complexity program") OR ("using in python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using computational and complexity program\") OR (\"using in python python programming\"))".
• Removing quotes may allow a broader search: (( using computational and complexity program ) OR ( using in python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("using computational and complexity program") OR ("using in python python programming"))*.
