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)
"elements carlo algorithm" » "elements search algorithm" (Expand Search), "elements colony algorithm" (Expand Search), "elements crcy algorithm" (Expand Search)
"elemental iron algorithm" » "elemental pso algorithm" (Expand Search), "elemental ii algorithm" (Expand Search), "elemental cnn 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: (((("elemental iron algorithm") OR ("elements carlo algorithm"))) OR ("element mapping algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elemental iron algorithm\") OR (\"elements carlo algorithm\"))) OR (\"element mapping algorithm\"))".
• Removing quotes may allow a broader search: (((( elemental iron algorithm ) OR ( elements carlo algorithm ))) OR ( element mapping algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elemental iron algorithm") OR ("elements carlo algorithm"))) OR ("element mapping algorithm"))*.
