Perhaps you should try some spelling variations:
"patient samples algorithm" » "patient sampling algorithm" (Expand Search), "patient kepler algorithm" (Expand Search), "patient atlas algorithm" (Expand Search), "sediment samples algorithm" (Expand Search)
"element mapping algorithm" » "element making algorithm" (Expand Search), "element mining algorithm" (Expand Search), "element learning algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "argument mapping algorithm" (Expand Search)
"elements wt algorithm" » "elements _ algorithm" (Expand Search), "elements ii algorithm" (Expand Search), "elements rf algorithm" (Expand Search), "elements b algorithm" (Expand Search), "elements fe 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: (("elements wt algorithm") OR ((("patient samples algorithm") OR ("element mapping algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements wt algorithm\") OR (((\"patient samples algorithm\") OR (\"element mapping algorithm\"))))".
• Removing quotes may allow a broader search: (( elements wt algorithm ) OR ((( patient samples algorithm ) OR ( element mapping algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements wt algorithm") OR ((("patient samples algorithm") OR ("element mapping algorithm"))))*.
