Perhaps you should try some spelling variations:
"implement routing algorithm" » "implement routine algorithm" (Expand Search), "implement modeling algorithm" (Expand Search), "implement finding algorithm" (Expand Search), "implement making algorithm" (Expand Search)
"movement data algorithms" » "movement art algorithms" (Expand Search), "movement all algorithms" (Expand Search), "movement both algorithms" (Expand Search)
"element mesh algorithm" » "element best algorithm" (Expand Search), "element mean algorithm" (Expand Search), "element means algorithm" (Expand Search), "element method algorithm" (Expand Search), "elements mges algorithm" (Expand Search), "element te algorithm" (Expand Search)

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("movement data algorithms") OR ((("implement routing algorithm") OR ("element mesh algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"movement data algorithms\") OR (((\"implement routing algorithm\") OR (\"element mesh algorithm\"))))".
• Removing quotes may allow a broader search: (( movement data algorithms ) OR ((( implement routing algorithm ) OR ( element mesh algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("movement data algorithms") OR ((("implement routing algorithm") OR ("element mesh algorithm"))))*.
