Perhaps you should try some spelling variations:
"advanced computational _ computer program" » "and computational _ computer program" (Expand search), "based computational _ computer program" (Expand search), "advanced computationsal _ computer program" (Expand search), "advance computationalal _ computer program" (Expand search), "advanced calculational _ computer program" (Expand search)
"advanced computation in example program" » "advanced computations in example program" (Expand search), "advance computational in example program" (Expand search), "advanced calculation in example program" (Expand search), "advanced computation and example program" (Expand search), "advanced computation of example program" (Expand search), "advanced imputation in example program" (Expand search), "advanced computation an example program" (Expand search), "advanced computation on example 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 computational _ computer program\") OR (\"advanced computation in example program\"))~".
• Removing quotes may allow a broader search: (( advanced computational _ computer program ) OR ( advanced computation in example program ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computational _ computer program") OR ("advanced computation in example program"))*.
