Perhaps you should try some spelling variations:
"level modeling algorithm" » "level making algorithm" (Expand Search), "novel modelling algorithm" (Expand Search), "element modeling algorithm" (Expand Search)
"complement based algorithm" » "complement past algorithm" (Expand Search), "complement cascade algorithm" (Expand Search), "complement system algorithm" (Expand Search)
"element data algorithms" » "element art algorithms" (Expand Search), "element all algorithms" (Expand Search), "element both algorithms" (Expand Search), "settlement data algorithms" (Expand Search), "relevant data algorithms" (Expand Search), "movement data algorithms" (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: (((("complement based algorithm") OR ("element data algorithms"))) OR ("level modeling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"complement based algorithm\") OR (\"element data algorithms\"))) OR (\"level modeling algorithm\"))".
• Removing quotes may allow a broader search: (((( complement based algorithm ) OR ( element data algorithms ))) OR ( level modeling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("complement based algorithm") OR ("element data algorithms"))) OR ("level modeling algorithm"))*.
