Perhaps you should try some spelling variations:
"element mapping algorithm" » "element sampling algorithm" (Expand Search), "element matching algorithm" (Expand Search), "element mining algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search), "element modeling algorithm" (Expand Search)
"element swarm algorithm" » "element search algorithm" (Expand Search), "element software algorithm" (Expand Search)
"element de algorithms" » "element _ algorithms" (Expand Search), "element ml algorithms" (Expand Search), "element rl algorithms" (Expand Search), "element te algorithms" (Expand Search), "element ree algorithms" (Expand Search), "element ore algorithms" (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element de algorithms\") OR (\"element swarm algorithm\"))) OR (\"element mapping algorithm\"))~".
• Removing quotes may allow a broader search: (((( element de algorithms ) OR ( element swarm algorithm ))) OR ( element mapping algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("element de algorithms") OR ("element swarm algorithm"))) OR ("element mapping algorithm"))*.
