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 pdm python programming" » "ising model pdm python programming" (Expand search), "using modis pdm python programming" (Expand search), "using mobile pdm python programming" (Expand search), "using model pytm python programming" (Expand search), "using model mda python programming" (Expand search), "using model pom python programming" (Expand search), "using model p python programming" (Expand search), "using model pi 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 computational using computer program\") OR (\"using model pdm python programming\"))~".
• Removing quotes may allow a broader search: (( based computational using computer program ) OR ( using model pdm python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computational using computer program") OR ("using model pdm python programming"))*.
