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)
"element ml algorithms" » "element _ algorithms" (Expand Search), "element g algorithms" (Expand Search), "element te algorithms" (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: (((("elements fusion algorithm") OR ("element ml algorithms"))) OR ("level coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements fusion algorithm\") OR (\"element ml algorithms\"))) OR (\"level coding algorithm\"))".
• Removing quotes may allow a broader search: (((( elements fusion algorithm ) OR ( element ml algorithms ))) OR ( level coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements fusion algorithm") OR ("element ml algorithms"))) OR ("level coding algorithm"))*.
