Perhaps you should try some spelling variations:
"based computational using computer program" » "and computational using computer program" (Expand search), "by computational using computer program" (Expand search), "based computation using computer program" (Expand search), "based computations using computer program" (Expand search), "based computacional usinas computer program" (Expand search)
"and simulation from coding program" » "and simulation from cloning program" (Expand search), "and simulation from loading program" (Expand search), "and simulation from cooling programs" (Expand search), "and simulation from decoding program" (Expand search), "and simulation from cooking program" (Expand search), "and simulation from codium program" (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: "((\"based computational using computer program\") OR (\"and simulation from coding program\"))~".
• Removing quotes may allow a broader search: (( based computational using computer program ) OR ( and simulation from coding program ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computational using computer program") OR ("and simulation from coding program"))*.
