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 wsd algorithm" » "complement c4d algorithm" (Expand Search), "complement past algorithm" (Expand Search), "complement _ algorithm" (Expand Search), "complement wold algorithm" (Expand Search), "complement pso algorithm" (Expand Search), "complement based 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: (((("complement wsd algorithm") OR ("element control algorithms"))) OR ("level coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"complement wsd algorithm\") OR (\"element control algorithms\"))) OR (\"level coding algorithm\"))".
• Removing quotes may allow a broader search: (((( complement wsd algorithm ) OR ( element control algorithms ))) OR ( level coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("complement wsd algorithm") OR ("element control algorithms"))) OR ("level coding algorithm"))*.
