Perhaps you should try some spelling variations:
"advanced simulation and computer program" » "advanced modulation and computer program" (Expand search), "advanced calculation and computer program" (Expand search), "advanced simulation _ computer program" (Expand search)
"advanced simulation from computation program" » "advanced modulation from computation program" (Expand search), "advanced calculation from computation program" (Expand search), "advanced simulation from computational program" (Expand search), "advanced simulation from computational programs" (Expand search), "advanced simulation from compensation program" (Expand search), "advanced simulation from competition program" (Expand search), "advanced simulation flow computation 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 and computer program") OR ("advanced simulation from computation program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced simulation and computer program\") OR (\"advanced simulation from computation program\"))*".
• Removing quotes may allow a broader search: (( advanced simulation and computer program ) OR ( advanced simulation from computation program ))*.
