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 code computing program" » "_ computational model computing program" (Expand search), "_ computational cost computing program" (Expand search), "_ computational models computing program" (Expand search), "_ computational code consulting program" (Expand search), "_ computational code computer program" (Expand search), "_ computational code computador program" (Expand search), "_ computational modern computing program" (Expand search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("_ computational code computing program") OR ("advanced computation in simplex program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"_ computational code computing program\") OR (\"advanced computation in simplex program\"))".
• Removing quotes may allow a broader search: (( _ computational code computing program ) OR ( advanced computation in simplex program )).
• Adding a wildcard symbol may retrieve word variants: (("_ computational code computing program") OR ("advanced computation in simplex program"))*.
