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