Perhaps you should try some spelling variations:
"elements fusion algorithm" » "elements lasso algorithm" (Expand Search), "elements upon 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)
"complement past algorithm" » "complement 5a algorithm" (Expand Search), "complement system algorithm" (Expand Search), "complement rast algorithm" (Expand Search), "complement pass algorithm" (Expand Search), "complement pso algorithm" (Expand Search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"complement past algorithm\") OR (\"elements fusion algorithm\"))) OR (\"level coding algorithm\"))~".
• Removing quotes may allow a broader search: (((( complement past algorithm ) OR ( elements fusion algorithm ))) OR ( level coding algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("complement past algorithm") OR ("elements fusion algorithm"))) OR ("level coding algorithm"))*.
