Perhaps you should try some spelling variations:
"objective functions _ computational code" » "objective function _ computational code" (Expand search), "executive functions _ computational code" (Expand search), "objective functions _ computational model" (Expand search), "objective functions _ computational cost" (Expand search), "objective functions _ computational models" (Expand search)
"using coding python python programming" » "using codigo python python programming" (Expand search), "using codigos python python programming" (Expand search), "using using python python programming" (Expand search), "using coding pythons python programming" (Expand search), "using coding piton python programming" (Expand search), "using coding pitons python programming" (Expand search), "using coping python python programming" (Expand search), "using coating python python programming" (Expand search), "using cooking python 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: "((\"objective functions _ computational code\") OR (\"using coding python python programming\"))~".
• Removing quotes may allow a broader search: (( objective functions _ computational code ) OR ( using coding python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("objective functions _ computational code") OR ("using coding python python programming"))*.
