Perhaps you should try some spelling variations:
"advanced computational and computer program" » "and computational and computer program" (Expand search), "based computational and computer program" (Expand search), "advanced computationsal and computer program" (Expand search), "advance computationalal and computer program" (Expand search), "advanced calculational and computer program" (Expand search), "advanced computational fluid computer program" (Expand search), "advanced computational _ computer program" (Expand search)
"advanced computation from simplex program" » "advanced computations from simplex program" (Expand search), "advance computational from simplex program" (Expand search), "advanced calculation from simplex program" (Expand search), "advanced competition from simplex program" (Expand search), "advanced amputation from simplex program" (Expand search), "advanced complication from simplex program" (Expand search), "advanced computation from simples program" (Expand search), "advanced computation from complex program" (Expand search), "advanced computation from simple program" (Expand search), "advanced computation from simpler 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 and computer program\") OR (\"advanced computation from simplex program\"))~".
• Removing quotes may allow a broader search: (( advanced computational and computer program ) OR ( advanced computation from simplex program ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computational and computer program") OR ("advanced computation from simplex program"))*.
