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)
"using computational and computation program" » "and computational and computation program" (Expand search), "using computational and computational program" (Expand search), "using computational and computational programs" (Expand search), "using computational and compensation program" (Expand search), "using computational fluid computation program" (Expand search), "using computational of 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 from complex program") OR ("using computational and computation program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced simulation from complex program\") OR (\"using computational and computation program\"))".
• Removing quotes may allow a broader search: (( advanced simulation from complex program ) OR ( using computational and computation program )).
• Adding a wildcard symbol may retrieve word variants: (("advanced simulation from complex program") OR ("using computational and computation program"))*.
