Perhaps you should try some spelling variations:
"advanced computation and complex program" » "advanced computations and complex program" (Expand search), "advanced computational and complex program" (Expand search), "advance computational and complex program" (Expand search), "advanced computation of complex program" (Expand search), "advanced computation and simplex program" (Expand search), "advanced computation and complex programmes" (Expand search), "advanced computation and complex prograded" (Expand search)
"using computational grids computer program" » "and computational grids computer program" (Expand search), "using computational and computer program" (Expand search), "using computational design computer 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: "((\"using computational grids computer program\") OR (\"advanced computation and complex program\"))~".
• Removing quotes may allow a broader search: (( using computational grids computer program ) OR ( advanced computation and complex program ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computational grids computer program") OR ("advanced computation and complex program"))*.
