Perhaps you should try some spelling variations:
"data modeling algorithm" » "data scheduling algorithm" (Expand Search), "data models algorithm" (Expand Search), "spatial modeling algorithm" (Expand Search)
"dbscan clustering algorithm" » "data clustering algorithm" (Expand Search)
"element td3 algorithm" » "element rd algorithm" (Expand Search), "elements td3 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: (((("data modeling algorithm") OR ("dbscan clustering algorithm"))) OR ("element td3 algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data modeling algorithm\") OR (\"dbscan clustering algorithm\"))) OR (\"element td3 algorithm\"))".
• Removing quotes may allow a broader search: (((( data modeling algorithm ) OR ( dbscan clustering algorithm ))) OR ( element td3 algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data modeling algorithm") OR ("dbscan clustering algorithm"))) OR ("element td3 algorithm"))*.
