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