Perhaps you should try some spelling variations:
"based computational code computing program" » "and computational code computing program" (Expand search), "by computational code computing program" (Expand search), "based computational model computing program" (Expand search), "based computational cost computing program" (Expand search), "based computational models computing program" (Expand search), "based computational code consulting program" (Expand search), "based computational code computador program" (Expand search), "based computational code computer programs" (Expand search), "based computational modern computing program" (Expand search)
"using computation is computer program" » "using computational is computer program" (Expand search), "using imputation is computer program" (Expand search), "using compilation is computer program" (Expand search), "using computation in computer program" (Expand search), "using computation of computer program" (Expand search), "using computation _ computer program" (Expand search), "using computation dcis computer program" (Expand search), "using computation icms computer program" (Expand search), "using computation gps computer program" (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: (("based computational code computing program") OR ("using computation is computer program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computational code computing program\") OR (\"using computation is computer program\"))".
• Removing quotes may allow a broader search: (( based computational code computing program ) OR ( using computation is computer program )).
• Adding a wildcard symbol may retrieve word variants: (("based computational code computing program") OR ("using computation is computer program"))*.
