Perhaps you should try some spelling variations:
"and computational code clustering problem" » "and computational model clustering problem" (Expand search), "and computational cost clustering problem" (Expand search), "and computational models clustering problem" (Expand search), "and computational code covering problem" (Expand search), "_ computational code clustering problem" (Expand search), "and computational co clustering problem" (Expand search), "and computational module clustering problem" (Expand search)
"using computation in coding program" » "using computational in coding program" (Expand search), "using imputation in coding program" (Expand search), "using compilation in coding program" (Expand search), "using computation and coding program" (Expand search), "using computation of coding program" (Expand search), "using computation in cloning program" (Expand search), "using computation in loading program" (Expand search), "using computation in cooling programs" (Expand search), "using computation on coding program" (Expand search), "using computation in decoding program" (Expand search), "using computation non coding 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 code clustering problem") OR ("using computation in coding program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"and computational code clustering problem\") OR (\"using computation in coding program\"))".
• Removing quotes may allow a broader search: (( and computational code clustering problem ) OR ( using computation in coding program )).
• Adding a wildcard symbol may retrieve word variants: (("and computational code clustering problem") OR ("using computation in coding program"))*.
