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)
"advanced computation from simplex program" » "advanced computations from simplex program" (Expand search), "advanced computational from simplex program" (Expand search), "advance computational 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 computation and computer program\") OR (\"advanced computation from simplex program\"))~".
• Removing quotes may allow a broader search: (( advanced computation and computer program ) OR ( advanced computation from simplex program ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computation and computer program") OR ("advanced computation from simplex program"))*.
