Perhaps you should try some spelling variations:
"implement modeling algorithm" » "element modeling algorithm" (Expand Search), "element modelling algorithm" (Expand Search), "implement making algorithm" (Expand Search)
"level using algorithm" » "level using algorithms" (Expand Search), "level routing algorithm" (Expand Search), "level fusion algorithm" (Expand Search), "levels using algorithm" (Expand Search)
"elements uce algorithms" » "elements mcem algorithms" (Expand Search), "elements de algorithms" (Expand Search), "elements five algorithms" (Expand Search), "elements ices algorithms" (Expand Search), "elements fe algorithms" (Expand Search), "elements ree 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: (((("implement modeling algorithm") OR ("elements uce algorithms"))) OR ("level using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"implement modeling algorithm\") OR (\"elements uce algorithms\"))) OR (\"level using algorithm\"))".
• Removing quotes may allow a broader search: (((( implement modeling algorithm ) OR ( elements uce algorithms ))) OR ( level using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("implement modeling algorithm") OR ("elements uce algorithms"))) OR ("level using algorithm"))*.
