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