Perhaps you should try some spelling variations:
"based computational using computer program" » "and computational using computer program" (Expand search), "by computational using computer program" (Expand search), "based computation using computer program" (Expand search), "based computations using computer program" (Expand search), "based computacional usinas computer program" (Expand search)
"using model lambda python programming" » "using modelo lambda python programming" (Expand search), "using model land python programming" (Expand search), "using modelo lambdacdm python programming" (Expand search), "ising model lambda python programming" (Expand search), "using modis lambda python programming" (Expand search), "using mobile lambda 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 using computer program") OR ("using model lambda python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computational using computer program\") OR (\"using model lambda python programming\"))*".
• Removing quotes may allow a broader search: (( based computational using computer program ) OR ( using model lambda python programming ))*.
