Perhaps you should try some spelling variations:
"advanced computation and computer program" » "advanced computations and computer program" (Expand search), "advanced computational and computer program" (Expand search), "advance computational and computer program" (Expand search), "advanced computation of computer program" (Expand search), "advanced computation _ computer program" (Expand search)
"advanced simulation code computer program" » "advanced modulation code computer program" (Expand search), "advanced calculation code computer program" (Expand search), "advanced simulation model computer program" (Expand search), "advanced simulation case computer program" (Expand search), "advanced simulation models computer program" (Expand search), "advanced simulation node computer program" (Expand search), "advanced simulation one computer program" (Expand search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced simulation code computer program\") OR (\"advanced computation and computer program\"))~".
• Removing quotes may allow a broader search: (( advanced simulation code computer program ) OR ( advanced computation and computer program ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced simulation code computer program") OR ("advanced computation and computer program"))*.
