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