Perhaps you should try some spelling variations:
"elements within algorithm" » "elements switching algorithm" (Expand Search), "elements twisting algorithm" (Expand Search), "elements matching algorithm" (Expand Search)
"level coding algorithm" » "level cosine algorithm" (Expand Search), "level modeling algorithm" (Expand Search), "level finding algorithm" (Expand Search), "level according algorithm" (Expand Search), "level using algorithm" (Expand Search)
"element both algorithms" » "element art algorithms" (Expand Search), "element four algorithms" (Expand Search), "element box algorithm" (Expand Search), "element data algorithms" (Expand Search), "element te algorithms" (Expand Search), "element mesh algorithms" (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 both algorithms") OR ((("elements within algorithm") OR ("level coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element both algorithms\") OR (((\"elements within algorithm\") OR (\"level coding algorithm\"))))".
• Removing quotes may allow a broader search: (( element both algorithms ) OR ((( elements within algorithm ) OR ( level coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element both algorithms") OR ((("elements within algorithm") OR ("level coding algorithm"))))*.
