Perhaps you should try some spelling variations:
"based computational in modeling problems" » "and computational in modeling problems" (Expand search), "by computational in modeling problems" (Expand search), "based computational in modelling problems" (Expand search), "based computational in modelling problem" (Expand search), "based computational in modeling process" (Expand search), "based computational and modeling problems" (Expand search), "based computational _ modeling problems" (Expand search), "based computational 3d modeling problems" (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 computational in modeling problems") OR ("using in python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computational in modeling problems\") OR (\"using in python python programming\"))".
• Removing quotes may allow a broader search: (( based computational in modeling problems ) OR ( using in python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("based computational in modeling problems") OR ("using in python python programming"))*.
