Perhaps you should try some spelling variations:
"advanced duplication and computer program" » "advanced application and computer program" (Expand search), "advanced applications and computer program" (Expand search), "advanced glication and computer program" (Expand search), "advanced replication and computer program" (Expand search), "advanced duplication in computer program" (Expand search), "advanced duplication _ computer program" (Expand search)
"based computation with computation program" » "based computation with computational program" (Expand search), "based computation with computational programs" (Expand search), "based computation with compensation program" (Expand search), "based computational with computation program" (Expand search), "based competition with computation program" (Expand search), "based compilation with computation program" (Expand search), "based complexation with computation program" (Expand search), "based composition with computation program" (Expand search), "based computation pitch computation program" (Expand search), "based computation path 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 duplication and computer program\") OR (\"based computation with computation program\"))~".
• Removing quotes may allow a broader search: (( advanced duplication and computer program ) OR ( based computation with computation program ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced duplication and computer program") OR ("based computation with computation program"))*.
