Perhaps you should try some spelling variations:
"experiments based algorithm" » "experiments showed algorithm" (Expand Search), "experimental basis algorithm" (Expand Search), "experimental case algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"element iron algorithm" » "element ii algorithm" (Expand Search), "element pso algorithm" (Expand Search), "element rf algorithm" (Expand Search), "elemental iron algorithm" (Expand Search), "element group algorithm" (Expand Search), "elements upon 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: (("experiments based algorithm") OR ((("element iron algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"experiments based algorithm\") OR (((\"element iron algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( experiments based algorithm ) OR ((( element iron algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("experiments based algorithm") OR ((("element iron algorithm") OR ("neural coding algorithm"))))*.
