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 code computing program" » "and computational code computing program" (Expand search), "using computational model computing program" (Expand search), "using computational cost computing program" (Expand search), "using computational models computing program" (Expand search), "using computational code consulting program" (Expand search), "using computational code computer program" (Expand search), "using computational code computador program" (Expand search), "using computational modern computing 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 code computing program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced simulation from complex program\") OR (\"using computational code computing program\"))*".
• Removing quotes may allow a broader search: (( advanced simulation from complex program ) OR ( using computational code computing program ))*.
