Perhaps you should try some spelling variations:
"using computational complexity computer program" » "and computational complexity computer program" (Expand search), "using computational complexity complex program" (Expand search), "using computational complexity computacao program" (Expand search), "using computational complexity competences program" (Expand search)
"code computation on coding program" » "core computation on coding program" (Expand search), "code computational on coding program" (Expand search), "pose computation on coding program" (Expand search), "code computation of coding program" (Expand search), "code computation in coding program" (Expand search), "code computation and coding program" (Expand search), "code computation on cloning program" (Expand search), "code computation on loading program" (Expand search), "code computation on cooling programs" (Expand search), "code computation 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: "((\"code computation on coding program\") OR (\"using computational complexity computer program\"))~".
• Removing quotes may allow a broader search: (( code computation on coding program ) OR ( using computational complexity computer program ))~.
• Adding a wildcard symbol may retrieve word variants: (("code computation on coding program") OR ("using computational complexity computer program"))*.
