Perhaps you should try some spelling variations:
"based computations using computer program" » "based computation using computer program" (Expand search), "based computational using computer program" (Expand search), "based competition using computer program" (Expand search), "based populations using computer program" (Expand search), "based computations in computer program" (Expand search)
"using mode from python programming" » "using mode from pathogen programming" (Expand search), "using mode from anthony programming" (Expand search), "using model from python programming" (Expand search), "using modern from python programming" (Expand search), "using models from python programming" (Expand search), "using modes from python programming" (Expand search), "using made from 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: "((\"based computations using computer program\") OR (\"using mode from python programming\"))~".
• Removing quotes may allow a broader search: (( based computations using computer program ) OR ( using mode from python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computations using computer program") OR ("using mode from python programming"))*.
