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