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 duplication in computation program" » "advanced application in computation program" (Expand search), "advanced applications in computation program" (Expand search), "advanced glication in computation program" (Expand search), "advanced duplication in computational program" (Expand search), "advanced duplication in computational programs" (Expand search), "advanced duplication in compensation program" (Expand search), "advanced replication in computation program" (Expand search), "advanced implication in computation program" (Expand search), "advanced duplication on computation program" (Expand search), "advanced duplication and computation 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 duplication in computation program\"))~".
• Removing quotes may allow a broader search: (( advanced computation and computer program ) OR ( advanced duplication in computation program ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computation and computer program") OR ("advanced duplication in computation program"))*.
