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)
"and complications in coding program" » "and implications in coding program" (Expand search), "and communications in coding program" (Expand search), "and complications in cloning program" (Expand search), "and complications in loading program" (Expand search), "and complications in cooling programs" (Expand search), "and complications on coding program" (Expand search), "and complications in decoding program" (Expand search), "and complications non coding 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: "((\"and complications in coding program\") OR (\"using computational complexity complex program\"))~".
• Removing quotes may allow a broader search: (( and complications in coding program ) OR ( using computational complexity complex program ))~.
• Adding a wildcard symbol may retrieve word variants: (("and complications in coding program") OR ("using computational complexity complex program"))*.
