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 replication from complex program" » "advanced application from complex program" (Expand search), "advanced applications from complex program" (Expand search), "advanced glication from complex program" (Expand search), "advanced complication from complex program" (Expand search), "advanced replication error complex program" (Expand search), "advanced replication from simplex program" (Expand search), "advanced replication from complex programmes" (Expand search), "advanced replication from complex prograded" (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 replication from complex program\"))~".
• Removing quotes may allow a broader search: (( advanced computation and computer program ) OR ( advanced replication from complex program ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computation and computer program") OR ("advanced replication from complex program"))*.
