Perhaps you should try some spelling variations:
"element mapping algorithm" » "element sampling algorithm" (Expand Search), "element matching algorithm" (Expand Search), "element learning algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search), "element modeling algorithm" (Expand Search)
"element mining algorithm" » "element learning algorithm" (Expand Search), "element means algorithm" (Expand Search), "element bonding algorithm" (Expand Search), "element modeling algorithm" (Expand Search)
"effects model algorithm" » "effects novel algorithm" (Expand Search), "effects forest algorithm" (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 mapping algorithm\") OR (\"element mining algorithm\"))) OR (\"effects model algorithm\"))~".
• Removing quotes may allow a broader search: (((( element mapping algorithm ) OR ( element mining algorithm ))) OR ( effects model algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("element mapping algorithm") OR ("element mining algorithm"))) OR ("effects model algorithm"))*.
