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