Perhaps you should try some spelling variations:
"using computational patrol routing problems" » "using computational paths routing problems" (Expand search), "using computational pathology routing problems" (Expand search), "using computational platform routing problems" (Expand search), "and computational patrol routing problems" (Expand search), "using computational patrol routing problem" (Expand search), "using computational patrol solving problems" (Expand search), "using computational patrol packing problems" (Expand search), "using computational path 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: (("using computational patrol routing problems") OR ("using population in coding program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using computational patrol routing problems\") OR (\"using population in coding program\"))".
• Removing quotes may allow a broader search: (( using computational patrol routing problems ) OR ( using population in coding program )).
• Adding a wildcard symbol may retrieve word variants: (("using computational patrol routing problems") OR ("using population in coding program"))*.
