Perhaps you should try some spelling variations:
"advanced computational and computer program" » "and computational and computer program" (Expand search), "based computational and computer program" (Expand search), "advanced computational fluid computer program" (Expand search), "advanced computational _ computer program" (Expand search)
"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)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("advanced computational and computer program") OR ("advanced simulation from complex program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced computational and computer program\") OR (\"advanced simulation from complex program\"))*".
• Removing quotes may allow a broader search: (( advanced computational and computer program ) OR ( advanced simulation from complex program ))*.
