Perhaps you should try some spelling variations:
"and computational code some program" » "and computational model some program" (Expand search), "and computational cost some program" (Expand search), "and computational models some program" (Expand search), "_ computational code some program" (Expand search), "and computational code home program" (Expand search), "and computational code time program" (Expand search), "and computational code doce program" (Expand search)
"using python python python programming" » "using pythons python python programming" (Expand search), "using piton python python programming" (Expand search), "using pitons python python programming" (Expand search), "usando python python python programming" (Expand search), "in python 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: "((\"and computational code some program\") OR (\"using python python python programming\"))~".
• Removing quotes may allow a broader search: (( and computational code some program ) OR ( using python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and computational code some program") OR ("using python python python programming"))*.
