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)
"based computational code component program" » "and computational code component program" (Expand search), "by computational code component program" (Expand search), "based computational model component program" (Expand search), "based computational cost component program" (Expand search), "based computational models component program" (Expand search), "based computational code component diagram" (Expand search), "based computational code component property" (Expand search), "based computational code component protease" (Expand search), "based computational core component program" (Expand search), "based computational mode component program" (Expand search), "based computational mode components 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 (\"based computational code component program\"))~".
• Removing quotes may allow a broader search: (( advanced computation and computer program ) OR ( based computational code component program ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computation and computer program") OR ("based computational code component program"))*.
