Perhaps you should try some spelling variations:
"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)
"elements under algorithm" » "elements new algorithm" (Expand Search), "elements tide algorithm" (Expand Search), "elements kepler algorithm" (Expand Search), "elements tended algorithm" (Expand Search), "sediments under algorithm" (Expand Search), "elements over algorithm" (Expand Search)
"element modbo algorithm" » "element model 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 under algorithm") OR ((("element modbo algorithm") OR ("level coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements under algorithm\") OR (((\"element modbo algorithm\") OR (\"level coding algorithm\"))))".
• Removing quotes may allow a broader search: (( elements under algorithm ) OR ((( element modbo algorithm ) OR ( level coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements under algorithm") OR ((("element modbo algorithm") OR ("level coding algorithm"))))*.
