Perhaps you should try some spelling variations:
"element mapping algorithm" » "element sampling algorithm" (Expand Search), "element matching algorithm" (Expand Search), "element learning algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search), "element modeling algorithm" (Expand Search)
"element mining algorithm" » "element learning algorithm" (Expand Search), "element means algorithm" (Expand Search), "element bonding algorithm" (Expand Search), "element modeling algorithm" (Expand Search)
"sediment edna algorithm" » "sediment fedsam algorithm" (Expand Search), "sediment means algorithm" (Expand Search), "sediment wgcna 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: (("sediment edna algorithm") OR ((("element mapping algorithm") OR ("element mining algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"sediment edna algorithm\") OR (((\"element mapping algorithm\") OR (\"element mining algorithm\"))))".
• Removing quotes may allow a broader search: (( sediment edna algorithm ) OR ((( element mapping algorithm ) OR ( element mining algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("sediment edna algorithm") OR ((("element mapping algorithm") OR ("element mining algorithm"))))*.
