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)
"level coding algorithm" » "level cosine algorithm" (Expand Search), "level modeling algorithm" (Expand Search), "level finding algorithm" (Expand Search), "level according algorithm" (Expand Search), "level using algorithm" (Expand Search)
"movement rast algorithm" » "movement best algorithm" (Expand Search), "movement forest algorithm" (Expand Search), "movement based algorithm" (Expand Search), "movement task algorithm" (Expand Search), "movement cost algorithm" (Expand Search), "movement costs 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 rast algorithm") OR ((("implement routing algorithm") OR ("level coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"movement rast algorithm\") OR (((\"implement routing algorithm\") OR (\"level coding algorithm\"))))".
• Removing quotes may allow a broader search: (( movement rast algorithm ) OR ((( implement routing algorithm ) OR ( level coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("movement rast algorithm") OR ((("implement routing algorithm") OR ("level coding algorithm"))))*.
