Perhaps you should try some spelling variations:
"element centrality algorithm" » "element control algorithm" (Expand Search), "element generation algorithm" (Expand Search), "element density algorithm" (Expand Search), "elements centrality 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 c3 algorithm" » "complement _ algorithm" (Expand Search), "complement 5a algorithm" (Expand Search), "complement low algorithm" (Expand Search), "complement cc3d algorithm" (Expand Search), "complement cnn algorithm" (Expand Search), "complement td3 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: (((("element centrality algorithm") OR ("complement c3 algorithm"))) OR ("level coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element centrality algorithm\") OR (\"complement c3 algorithm\"))) OR (\"level coding algorithm\"))".
• Removing quotes may allow a broader search: (((( element centrality algorithm ) OR ( complement c3 algorithm ))) OR ( level coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element centrality algorithm") OR ("complement c3 algorithm"))) OR ("level coding algorithm"))*.
