Perhaps you should try some spelling variations:
"improvements routing algorithm" » "improvements using algorithm" (Expand Search), "improvements position algorithm" (Expand Search), "improvements modeling algorithm" (Expand Search), "improvements finding algorithm" (Expand Search), "improvements making algorithm" (Expand Search)
"data using algorithm" » "data using algorithms" (Expand Search), "data fusion algorithm" (Expand Search), "data making algorithm" (Expand Search)
"movement data algorithm" » "movement data algorithms" (Expand Search), "movement update algorithm" (Expand Search), "movement atlas 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: (((("improvements routing algorithm") OR ("movement data algorithm"))) OR ("data using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"improvements routing algorithm\") OR (\"movement data algorithm\"))) OR (\"data using algorithm\"))".
• Removing quotes may allow a broader search: (((( improvements routing algorithm ) OR ( movement data algorithm ))) OR ( data using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("improvements routing algorithm") OR ("movement data algorithm"))) OR ("data using algorithm"))*.
