Perhaps you should try some spelling variations:
"and computational tool routing problems" » "and computational biology routing problems" (Expand search), "_ computational tool routing problems" (Expand search), "and computational tool routing problem" (Expand search), "and computational tool solving problems" (Expand search), "and computational tool packing problems" (Expand search), "and computational tool coating problems" (Expand search), "and computational tool computing problems" (Expand search), "and computational patrol routing problems" (Expand search)
"using population in coding program" » "aging population in coding program" (Expand search), "ageing population in coding program" (Expand search), "young population in coding program" (Expand search), "using population in cloning program" (Expand search), "using population in loading program" (Expand search), "using population in cooling programs" (Expand search), "using population on coding program" (Expand search), "using population in decoding program" (Expand search), "using population 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 tool routing problems") OR ("using population in coding program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"and computational tool routing problems\") OR (\"using population in coding program\"))".
• Removing quotes may allow a broader search: (( and computational tool routing problems ) OR ( using population in coding program )).
• Adding a wildcard symbol may retrieve word variants: (("and computational tool routing problems") OR ("using population in coding program"))*.
