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 _ constructing program" » "advanced simulation _ consulting program" (Expand search), "advanced simulation _ reconstruction program" (Expand search), "advanced simulation _ constructing ronda" (Expand search), "advanced modulation _ constructing program" (Expand search), "advanced calculation _ constructing 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 computation and computer program\") OR (\"advanced simulation _ constructing program\"))~".
• Removing quotes may allow a broader search: (( advanced computation and computer program ) OR ( advanced simulation _ constructing program ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computation and computer program") OR ("advanced simulation _ constructing program"))*.
