Perhaps you should try some spelling variations:
"image processing algorithm" » "image modeling algorithm" (Expand Search), "image routing algorithm" (Expand Search), "image tracking algorithm" (Expand Search)
"present data algorithm" » "present data algorithms" (Expand Search), "present update algorithm" (Expand Search), "present atlas algorithm" (Expand Search), "presence data algorithm" (Expand Search), "present day algorithm" (Expand Search), "recent data algorithm" (Expand Search)
"element erf algorithm" » "element rf algorithm" (Expand Search), "element rl algorithm" (Expand Search), "element em algorithm" (Expand Search), "element ore algorithm" (Expand Search), "element mesh 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 erf algorithm\") OR (\"present data algorithm\"))) OR (\"image processing algorithm\"))~".
• Removing quotes may allow a broader search: (((( element erf algorithm ) OR ( present data algorithm ))) OR ( image processing algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("element erf algorithm") OR ("present data algorithm"))) OR ("image processing algorithm"))*.
