Perhaps you should try some spelling variations:
"element contents algorithm" » "element consensus algorithm" (Expand Search), "element consistent algorithm" (Expand Search), "element control algorithm" (Expand Search), "element content algorithm" (Expand Search), "pigment contents algorithm" (Expand Search)
"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)

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