Perhaps you should try some spelling variations:
"complement based algorithm" » "complement past algorithm" (Expand Search), "complement cascade algorithm" (Expand Search), "complement system 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 task algorithm" » "movement rast algorithm" (Expand Search), "movement pass algorithm" (Expand Search), "movement lasso algorithm" (Expand Search), "movement data 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 task algorithm") OR ("complement based algorithm"))) OR ("level coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"movement task algorithm\") OR (\"complement based algorithm\"))) OR (\"level coding algorithm\"))".
• Removing quotes may allow a broader search: (((( movement task algorithm ) OR ( complement based algorithm ))) OR ( level coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("movement task algorithm") OR ("complement based algorithm"))) OR ("level coding algorithm"))*.
