Perhaps you should try some spelling variations:
"effects sampling algorithm" » "effects mining algorithm" (Expand Search), "effects modeling algorithm" (Expand Search), "effects along algorithm" (Expand Search), "effects arising algorithm" (Expand Search)
"element forest algorithm" » "element ore algorithm" (Expand Search)
"elements pso algorithm" » "elements two algorithms" (Expand Search), "elements _ algorithm" (Expand Search), "elements new algorithm" (Expand Search), "elements ppm algorithm" (Expand Search), "elements upon algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("element forest algorithm") OR ("elements pso algorithm"))) OR ("effects sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element forest algorithm\") OR (\"elements pso algorithm\"))) OR (\"effects sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( element forest algorithm ) OR ( elements pso algorithm ))) OR ( effects sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element forest algorithm") OR ("elements pso algorithm"))) OR ("effects sampling algorithm"))*.
