Perhaps you should try some spelling variations:
"level codingnb algorithm" » "level cosine algorithm" (Expand Search), "level coding algorithm" (Expand Search)
"element mesh algorithm" » "element best algorithm" (Expand Search), "element mean algorithm" (Expand Search), "element means algorithm" (Expand Search), "element method algorithm" (Expand Search), "elements mges algorithm" (Expand Search), "element te algorithm" (Expand Search)
"element g algorithm" » "element _ algorithm" (Expand Search), "element b algorithm" (Expand Search), "element gnb algorithm" (Expand Search), "elements _ 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 g algorithm") OR ((("element mesh algorithm") OR ("level codingnb algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element g algorithm\") OR (((\"element mesh algorithm\") OR (\"level codingnb algorithm\"))))".
• Removing quotes may allow a broader search: (( element g algorithm ) OR ((( element mesh algorithm ) OR ( level codingnb algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element g algorithm") OR ((("element mesh algorithm") OR ("level codingnb algorithm"))))*.
