Perhaps you should try some spelling variations:
"effects sampling algorithm" » "effects making algorithm" (Expand Search), "effects modeling algorithm" (Expand Search), "effects mining algorithm" (Expand Search), "effects along algorithm" (Expand Search), "effects arising algorithm" (Expand Search)
"levels using algorithm" » "levels using algorithms" (Expand Search), "levels routing algorithm" (Expand Search), "levels fusion algorithm" (Expand Search), "level using algorithm" (Expand Search), "models using algorithm" (Expand Search), "cells 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: (("movement data algorithm") OR ((("effects sampling algorithm") OR ("levels using algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"movement data algorithm\") OR (((\"effects sampling algorithm\") OR (\"levels using algorithm\"))))".
• Removing quotes may allow a broader search: (( movement data algorithm ) OR ((( effects sampling algorithm ) OR ( levels using algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("movement data algorithm") OR ((("effects sampling algorithm") OR ("levels using algorithm"))))*.
