Perhaps you should try some spelling variations:
"elements sampling algorithm" » "elements mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "client sampling algorithm" (Expand Search)
"present forest algorithm" » "present free algorithm" (Expand Search)
"present cryo algorithm" » "present carlo algorithm" (Expand Search), "present trpo algorithm" (Expand Search), "present pso algorithm" (Expand Search), "present day 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: (((("present forest algorithm") OR ("present cryo algorithm"))) OR ("elements sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"present forest algorithm\") OR (\"present cryo algorithm\"))) OR (\"elements sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( present forest algorithm ) OR ( present cryo algorithm ))) OR ( elements sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("present forest algorithm") OR ("present cryo algorithm"))) OR ("elements sampling algorithm"))*.
