Perhaps you should try some spelling variations:
"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 means algorithm" » "element search algorithm" (Expand Search), "element mesh algorithm" (Expand Search)
"implement ipca algorithm" » "implement wgcna algorithm" (Expand Search), "implement cscap algorithm" (Expand Search), "implement ii algorithm" (Expand Search), "implemented ipca algorithm" (Expand Search), "implementing ipca 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: (((("implement ipca algorithm") OR ("element means algorithm"))) OR ("level coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"implement ipca algorithm\") OR (\"element means algorithm\"))) OR (\"level coding algorithm\"))".
• Removing quotes may allow a broader search: (((( implement ipca algorithm ) OR ( element means algorithm ))) OR ( level coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("implement ipca algorithm") OR ("element means algorithm"))) OR ("level coding algorithm"))*.
