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