Perhaps you should try some spelling variations:
"based computational and complexity from" » "and computational and complexity from" (Expand search), "by computational and complexity from" (Expand search), "based computational fluid complexity from" (Expand search)
"using model from python programming" » "ising model from python programming" (Expand search), "using modis from python programming" (Expand search), "using mobile from python programming" (Expand search), "using model from pathogen programming" (Expand search), "using model from anthony programming" (Expand search), "using models from 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 and complexity from") OR ("using model from python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computational and complexity from\") OR (\"using model from python programming\"))".
• Removing quotes may allow a broader search: (( based computational and complexity from ) OR ( using model from python programming )).
• Adding a wildcard symbol may retrieve word variants: (("based computational and complexity from") OR ("using model from python programming"))*.
