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)
"elements wgcna algorithm" » "elements cnn algorithm" (Expand Search)
"complement pass algorithm" » "complement past algorithm" (Expand Search), "complement 5a algorithm" (Expand Search), "complement lasso algorithm" (Expand Search), "complement pso algorithm" (Expand Search), "complement rast 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: (((("elements wgcna algorithm") OR ("complement pass algorithm"))) OR ("level coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements wgcna algorithm\") OR (\"complement pass algorithm\"))) OR (\"level coding algorithm\"))".
• Removing quotes may allow a broader search: (((( elements wgcna algorithm ) OR ( complement pass algorithm ))) OR ( level coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements wgcna algorithm") OR ("complement pass algorithm"))) OR ("level coding algorithm"))*.
