Perhaps you should try some spelling variations:
"using computational methods computation code" » "using computational model computation code" (Expand search), "and computational methods computation code" (Expand search), "using computational method computation code" (Expand search), "using computational methods computational code" (Expand search), "using computational methods comparation code" (Expand search), "using computational methods computation model" (Expand search), "using computational methods computation co" (Expand search)
"using codigo python python programming" » "using codigo pythons python programming" (Expand search), "using codigo piton python programming" (Expand search), "using codigo pitons python programming" (Expand search), "using indigo python python programming" (Expand search), "using coding python python programming" (Expand search), "using codium 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: "((\"using computational methods computation code\") OR (\"using codigo python python programming\"))~".
• Removing quotes may allow a broader search: (( using computational methods computation code ) OR ( using codigo python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computational methods computation code") OR ("using codigo python python programming"))*.
