Perhaps you should try some spelling variations:
"based computational model computer program" » "and computational model computer program" (Expand search), "by computational model computer program" (Expand search), "based computational modeling computer program" (Expand search), "based computational vhdl computer program" (Expand search)
"using model python python programming" » "using model pythons python programming" (Expand search), "using model piton python programming" (Expand search), "using model pitons python programming" (Expand search), "using modulo python python programming" (Expand search), "using monty python python programming" (Expand search), "using tool python python programming" (Expand search), "ising model python python programming" (Expand search), "using modis python python programming" (Expand search), "using mobile 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 model computer program") OR ("using model python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computational model computer program\") OR (\"using model python python programming\"))".
• Removing quotes may allow a broader search: (( based computational model computer program ) OR ( using model python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("based computational model computer program") OR ("using model python python programming"))*.
