Perhaps you should try some spelling variations:
"models using algorithms" » "models pacing algorithms" (Expand Search), "models nine algorithms" (Expand Search), "models sorting algorithms" (Expand Search), "model using algorithms" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"element rf algorithm" » "element _ algorithm" (Expand Search), "element ii algorithm" (Expand Search), "element art algorithms" (Expand Search), "element ore algorithm" (Expand Search), "element ree 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 rf algorithm\") OR (((\"models using algorithms\") OR (\"neural coding algorithm\"))))~".
• Removing quotes may allow a broader search: (( element rf algorithm ) OR ((( models using algorithms ) OR ( neural coding algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("element rf algorithm") OR ((("models using algorithms") OR ("neural coding algorithm"))))*.
