Perhaps you should try some spelling variations:
"based modeling algorithm" » "based making algorithm" (Expand Search), "based model algorithm" (Expand Search), "based models algorithm" (Expand Search)
"element based algorithms" » "element based algorithm" (Expand Search), "engagement based algorithms" (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: (("based modeling algorithm") OR ((("movement data algorithm") OR ("element based algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based modeling algorithm\") OR (((\"movement data algorithm\") OR (\"element based algorithms\"))))".
• Removing quotes may allow a broader search: (( based modeling algorithm ) OR ((( movement data algorithm ) OR ( element based algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("based modeling algorithm") OR ((("movement data algorithm") OR ("element based algorithms"))))*.
