Perhaps you should try some spelling variations:
"element content algorithm" » "element consistent algorithm" (Expand Search), "element control algorithm" (Expand Search), "element monte 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 ree algorithms" » "element tree algorithms" (Expand Search), "element three algorithms" (Expand Search), "element rl algorithms" (Expand Search), "elements ree algorithms" (Expand Search), "elements res algorithms" (Expand Search), "element te algorithms" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("element content algorithm") OR ("element ree algorithms"))) OR ("level coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element content algorithm\") OR (\"element ree algorithms\"))) OR (\"level coding algorithm\"))".
• Removing quotes may allow a broader search: (((( element content algorithm ) OR ( element ree algorithms ))) OR ( level coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element content algorithm") OR ("element ree algorithms"))) OR ("level coding algorithm"))*.
