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)
"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)
"present td3 algorithm" » "present cc3d algorithm" (Expand Search), "present _ algorithm" (Expand Search), "present ii algorithm" (Expand Search), "present tab algorithm" (Expand Search), "present study 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: (((("present td3 algorithm") OR ("element data algorithms"))) OR ("implement modeling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"present td3 algorithm\") OR (\"element data algorithms\"))) OR (\"implement modeling algorithm\"))".
• Removing quotes may allow a broader search: (((( present td3 algorithm ) OR ( element data algorithms ))) OR ( implement modeling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("present td3 algorithm") OR ("element data algorithms"))) OR ("implement modeling algorithm"))*.
