Perhaps you should try some spelling variations:
"advanced estimation in computer program" » "advanced automation in computer program" (Expand search), "advanced gestation in computer program" (Expand search), "advanced optimization in computer program" (Expand search), "advanced estimation of computer program" (Expand search), "advanced estimation _ computer program" (Expand search)
"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)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("advanced estimation in computer program") OR ("advanced simulation and computational program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced estimation in computer program\") OR (\"advanced simulation and computational program\"))".
• Removing quotes may allow a broader search: (( advanced estimation in computer program ) OR ( advanced simulation and computational program )).
• Adding a wildcard symbol may retrieve word variants: (("advanced estimation in computer program") OR ("advanced simulation and computational program"))*.
