Perhaps you should try some spelling variations:
"coder coder some computational code" » "coder coder the computational code" (Expand search), "coder coder based computational code" (Expand search), "coder coder _ computational code" (Expand search), "coder coder some computational model" (Expand search), "coder coder some computational cost" (Expand search), "coder coder some computational models" (Expand search), "coder decoder some computational code" (Expand search), "code code some computational code" (Expand search), "decoder codec some computational code" (Expand search), "coder code some computational code" (Expand search), "coder border some computational code" (Expand search), "coder over some computational code" (Expand search)
"on python python python programming" » "on pythons python python programming" (Expand search), "on piton python python programming" (Expand search), "on pitons python python programming" (Expand search), "in python pythin python programming" (Expand search), "of python pythof python programming" (Expand search), "_ python pyth_ 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: (("coder coder some computational code") OR ("on python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder coder some computational code\") OR (\"on python python python programming\"))".
• Removing quotes may allow a broader search: (( coder coder some computational code ) OR ( on python python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("coder coder some computational code") OR ("on python python python programming"))*.
