Perhaps you should try some spelling variations:
"based simulation and computation program" » "based simulation and computational program" (Expand search), "based simulation and computational programs" (Expand search), "based simulation and compensation program" (Expand search), "and simulation and computation program" (Expand search), "based simulation of computation program" (Expand search)
"by computational and computing program" » "by computational fluid computing program" (Expand search), "by computational and consulting program" (Expand search), "by computational and computer program" (Expand search), "by computational and computador program" (Expand search), "_ computational and computing program" (Expand search), "and computational and computing program" (Expand search), "by computational grid computing program" (Expand search), "by computational fog 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: (("by computational and computing program") OR ("based simulation and computation program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"by computational and computing program\") OR (\"based simulation and computation program\"))".
• Removing quotes may allow a broader search: (( by computational and computing program ) OR ( based simulation and computation program )).
• Adding a wildcard symbol may retrieve word variants: (("by computational and computing program") OR ("based simulation and computation program"))*.
