Perhaps you should try some spelling variations:
"elements custom algorithm" » "elements fusion algorithm" (Expand Search), "elements control algorithm" (Expand Search), "elements 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)
"relevant study algorithm" » "relevant wsindy algorithm" (Expand Search), "relevant td3 algorithm" (Expand Search), "relevant seu algorithm" (Expand Search), "relevant studies algorithm" (Expand Search), "recent study algorithm" (Expand Search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("elements custom algorithm") OR ("relevant study algorithm"))) OR ("level coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements custom algorithm\") OR (\"relevant study algorithm\"))) OR (\"level coding algorithm\"))".
• Removing quotes may allow a broader search: (((( elements custom algorithm ) OR ( relevant study algorithm ))) OR ( level coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements custom algorithm") OR ("relevant study algorithm"))) OR ("level coding algorithm"))*.
