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)
"effects main algorithm" » "effects making algorithm" (Expand Search), "effects magic algorithm" (Expand Search), "effects mean algorithm" (Expand Search), "effects using algorithm" (Expand Search), "affects maize algorithm" (Expand Search), "effects meta 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 forest algorithm") OR ((("effects sampling algorithm") OR ("effects main algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element forest algorithm\") OR (((\"effects sampling algorithm\") OR (\"effects main algorithm\"))))".
• Removing quotes may allow a broader search: (( element forest algorithm ) OR ((( effects sampling algorithm ) OR ( effects main algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element forest algorithm") OR ((("effects sampling algorithm") OR ("effects main algorithm"))))*.
