Perhaps you should try some spelling variations:
"using computational complexity complex program" » "and computational complexity complex program" (Expand search), "using computational complexity simplex program" (Expand search), "using computational complexity complex programmes" (Expand search), "using computational complexity complex prograded" (Expand search)
"by computational tool coding program" » "by computational biology coding program" (Expand search), "_ computational tool coding program" (Expand search), "and computational tool coding program" (Expand search), "by computational tool cloning program" (Expand search), "by computational tool loading program" (Expand search), "by computational tool cooling programs" (Expand search), "by computational tool coating program" (Expand search), "by computational tool cooking program" (Expand search), "by computational tool coatings 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: "((\"by computational tool coding program\") OR (\"using computational complexity complex program\"))~".
• Removing quotes may allow a broader search: (( by computational tool coding program ) OR ( using computational complexity complex program ))~.
• Adding a wildcard symbol may retrieve word variants: (("by computational tool coding program") OR ("using computational complexity complex program"))*.
