Perhaps you should try some spelling variations:
"element mining algorithm" » "element finding algorithm" (Expand Search), "element making algorithm" (Expand Search), "element training algorithms" (Expand Search), "element mapping algorithm" (Expand Search), "element bonding algorithm" (Expand Search), "element modeling algorithm" (Expand Search)
"present study algorithm" » "present wsindy algorithm" (Expand Search), "present td3 algorithm" (Expand Search), "present seu algorithm" (Expand Search)
"element ree algorithm" » "element tree algorithms" (Expand Search), "element new algorithm" (Expand Search), "element rf algorithm" (Expand Search), "elements ree algorithm" (Expand Search), "elements res algorithm" (Expand Search), "element te 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: (((("present study algorithm") OR ("element ree algorithm"))) OR ("element mining algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"present study algorithm\") OR (\"element ree algorithm\"))) OR (\"element mining algorithm\"))".
• Removing quotes may allow a broader search: (((( present study algorithm ) OR ( element ree algorithm ))) OR ( element mining algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("present study algorithm") OR ("element ree algorithm"))) OR ("element mining algorithm"))*.
