Perhaps you should try some spelling variations:
"element custom algorithm" » "element fusion algorithm" (Expand Search), "element control algorithm" (Expand Search), "element lasso 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)
"elements cscap algorithm" » "elements cc3d algorithm" (Expand Search), "elements ipca algorithm" (Expand Search), "elements cosine algorithm" (Expand Search), "elements crcy 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 custom algorithm") OR ("elements cscap algorithm"))) OR ("level coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element custom algorithm\") OR (\"elements cscap algorithm\"))) OR (\"level coding algorithm\"))".
• Removing quotes may allow a broader search: (((( element custom algorithm ) OR ( elements cscap algorithm ))) OR ( level coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element custom algorithm") OR ("elements cscap algorithm"))) OR ("level coding algorithm"))*.
