Perhaps you should try some spelling variations:
"element control algorithms" » "element control algorithm" (Expand Search), "element controls algorithms" (Expand Search), "element content algorithms" (Expand Search), "dependent control algorithms" (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)
"complement pass algorithm" » "complement past algorithm" (Expand Search), "complement 5a algorithm" (Expand Search), "complement lasso algorithm" (Expand Search), "complement pso algorithm" (Expand Search), "complement rast 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 control algorithms") OR ("complement pass algorithm"))) OR ("level coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element control algorithms\") OR (\"complement pass algorithm\"))) OR (\"level coding algorithm\"))".
• Removing quotes may allow a broader search: (((( element control algorithms ) OR ( complement pass algorithm ))) OR ( level coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element control algorithms") OR ("complement pass algorithm"))) OR ("level coding algorithm"))*.
