Perhaps you should try some spelling variations:
"element swarm algorithm" » "element search algorithm" (Expand Search), "element software algorithm" (Expand Search)
"element mesh algorithm" » "element best algorithm" (Expand Search), "element mean algorithm" (Expand Search), "element means algorithm" (Expand Search), "element method algorithm" (Expand Search)
"element forest algorithm" » "element ore 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: (((("element mesh algorithm") OR ("element swarm algorithm"))) OR ("element forest algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element mesh algorithm\") OR (\"element swarm algorithm\"))) OR (\"element forest algorithm\"))".
• Removing quotes may allow a broader search: (((( element mesh algorithm ) OR ( element swarm algorithm ))) OR ( element forest algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element mesh algorithm") OR ("element swarm algorithm"))) OR ("element forest algorithm"))*.
