Perhaps you should try some spelling variations:
"advanced simulation from complex program" » "advanced modulation from complex program" (Expand search), "advanced calculation from complex program" (Expand search), "advanced simulation from simplex program" (Expand search), "advanced simulation from complex programmes" (Expand search), "advanced simulation from complex prograded" (Expand search)
"based computational _ computation program" » "and computational _ computation program" (Expand search), "by computational _ computation program" (Expand search), "based computational _ computational program" (Expand search), "based computational _ computational programs" (Expand search), "based computational _ compensation 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: (("advanced simulation from complex program") OR ("based computational _ computation program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced simulation from complex program\") OR (\"based computational _ computation program\"))".
• Removing quotes may allow a broader search: (( advanced simulation from complex program ) OR ( based computational _ computation program )).
• Adding a wildcard symbol may retrieve word variants: (("advanced simulation from complex program") OR ("based computational _ computation program"))*.
