Perhaps you should try some spelling variations:
"elements mapping algorithm" » "elements making algorithm" (Expand Search), "elements mining algorithm" (Expand Search), "elements learning algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search), "elements during 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: (("element pso algorithm") OR ((("elements mapping algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element pso algorithm\") OR (((\"elements mapping algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( element pso algorithm ) OR ((( elements mapping algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element pso algorithm") OR ((("elements mapping algorithm") OR ("neural coding algorithm"))))*.
