Perhaps you should try some spelling variations:
"segment detection algorithm" » "event detection algorithm" (Expand Search), "recent detection algorithm" (Expand Search), "defect detection 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 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: (((("segment detection algorithm") OR ("movement data algorithm"))) OR ("level coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"segment detection algorithm\") OR (\"movement data algorithm\"))) OR (\"level coding algorithm\"))".
• Removing quotes may allow a broader search: (((( segment detection algorithm ) OR ( movement data algorithm ))) OR ( level coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("segment detection algorithm") OR ("movement data algorithm"))) OR ("level coding algorithm"))*.
