Perhaps you should try some spelling variations:
"elements presented algorithm" » "elements present algorithm" (Expand Search), "patients presented algorithm" (Expand Search), "elements related algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"element pso algorithm" » "element lasso algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element ii algorithm" (Expand Search), "element mesh algorithm" (Expand Search), "elements ppm 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: (("elements presented algorithm") OR ((("element pso algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements presented algorithm\") OR (((\"element pso algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( elements presented algorithm ) OR ((( element pso algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements presented algorithm") OR ((("element pso algorithm") OR ("neural coding algorithm"))))*.
