Perhaps you should try some spelling variations:
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean 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 cc3d algorithm" » "complement c3 algorithm" (Expand Search), "complement c4d algorithm" (Expand Search), "complement c5 algorithm" (Expand Search), "complement cscap algorithm" (Expand Search), "complement cnn algorithm" (Expand Search), "complement wold 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 cc3d algorithm") OR ("element method algorithm"))) OR ("level coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"complement cc3d algorithm\") OR (\"element method algorithm\"))) OR (\"level coding algorithm\"))".
• Removing quotes may allow a broader search: (((( complement cc3d algorithm ) OR ( element method algorithm ))) OR ( level coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("complement cc3d algorithm") OR ("element method algorithm"))) OR ("level coding algorithm"))*.
