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)
"advanced control base constraint program" » "advanced control base constraint programs" (Expand search), "advanced control base constraint programmig" (Expand search), "advanced control base constraint programing" (Expand search), "advanced control based constraints program" (Expand search), "advanced control task constraint program" (Expand search), "advanced control least constraint program" (Expand search), "advanced control based constraint program" (Expand search), "advanced controle base constraint program" (Expand search), "advanced control bases constraint 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 control base constraint program") OR ("advanced simulation from complex program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced control base constraint program\") OR (\"advanced simulation from complex program\"))".
• Removing quotes may allow a broader search: (( advanced control base constraint program ) OR ( advanced simulation from complex program )).
• Adding a wildcard symbol may retrieve word variants: (("advanced control base constraint program") OR ("advanced simulation from complex program"))*.
