Perhaps you should try some spelling variations:
"effects sampling algorithm" » "effects mining algorithm" (Expand Search), "effects along algorithm" (Expand Search), "effects arising algorithm" (Expand Search)
"effects modeling algorithm" » "effects mining algorithm" (Expand Search), "effects matching algorithm" (Expand Search), "effects boosting algorithm" (Expand Search), "effects model algorithm" (Expand Search), "effects models algorithm" (Expand Search), "effect model algorithm" (Expand Search)
"element ore algorithm" » "element rf algorithm" (Expand Search), "element rl algorithm" (Expand Search), "element erf algorithm" (Expand Search), "element te algorithm" (Expand Search), "element ree algorithm" (Expand Search), "element model 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 ore algorithm") OR ((("effects sampling algorithm") OR ("effects modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element ore algorithm\") OR (((\"effects sampling algorithm\") OR (\"effects modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( element ore algorithm ) OR ((( effects sampling algorithm ) OR ( effects modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element ore algorithm") OR ((("effects sampling algorithm") OR ("effects modeling algorithm"))))*.
