Perhaps you should try some spelling variations:
"advanced computation _ computing program" » "advanced computations _ computing program" (Expand search), "advanced computational _ computing program" (Expand search), "advance computational _ computing program" (Expand search), "advanced computation _ consulting program" (Expand search), "advanced computation _ computador program" (Expand search), "advanced computation _ computer programs" (Expand search)
"based compositional java computer program" » "base compositional java computer program" (Expand search), "based compositions java computer program" (Expand search), "varied compositional java computer program" (Expand search), "based compositional data computer program" (Expand search), "based compositional and computer program" (Expand search), "based compositional hard computer 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 _ computing program\") OR (\"based compositional java computer program\"))~".
• Removing quotes may allow a broader search: (( advanced computation _ computing program ) OR ( based compositional java computer program ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computation _ computing program") OR ("based compositional java computer program"))*.
