Perhaps you should try some spelling variations:
"advanced computation in simplex program" » "advanced computations in simplex program" (Expand search), "advanced computational in simplex program" (Expand search), "advance computational in simplex program" (Expand search), "advanced computation in simples program" (Expand search), "advanced computation in complex program" (Expand search), "advanced computation and simplex program" (Expand search), "advanced computation of simplex program" (Expand search), "advanced imputation in simplex program" (Expand search), "advanced computation in simple program" (Expand search), "advanced computation in simpler program" (Expand search), "advanced computation n simplex program" (Expand search)
"_ computational in computing program" » "_ computational in consulting program" (Expand search), "_ computational in computer program" (Expand search), "_ computational in computador program" (Expand search), "_ computational and computing program" (Expand search), "_ computational _ computing program" (Expand search), "_ computational 3d computing program" (Expand search), "_ computational of computing 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: "((\"_ computational in computing program\") OR (\"advanced computation in simplex program\"))~".
• Removing quotes may allow a broader search: (( _ computational in computing program ) OR ( advanced computation in simplex program ))~.
• Adding a wildcard symbol may retrieve word variants: (("_ computational in computing program") OR ("advanced computation in simplex program"))*.
