Perhaps you should try some spelling variations:
"based computational coder execution time" » "and computational coder execution time" (Expand search), "by computational coder execution time" (Expand search), "based computational code execution time" (Expand search), "based computational codes execution time" (Expand search), "based computational model execution time" (Expand search), "based computational over execution time" (Expand search)
"using _ python python programming" » "using _ pythons python programming" (Expand search), "using _ piton python programming" (Expand search), "using _ pitons 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 coder execution time") OR ("using _ python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computational coder execution time\") OR (\"using _ python python programming\"))".
• Removing quotes may allow a broader search: (( based computational coder execution time ) OR ( using _ python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("based computational coder execution time") OR ("using _ python python programming"))*.
