Perhaps you should try some spelling variations:
"entropy algorithm" » "error algorithm" (Expand Search)
"bhath algorithm" » "bat algorithm" (Expand Search), "search algorithm" (Expand Search), "states algorithm" (Expand Search)
"bath algorithm" » "bat algorithm" (Expand Search), "search algorithm" (Expand Search), "states algorithm" (Expand Search)
"el algoritmo" » "un algoritmo" (Expand Search), "de algoritmos" (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: (((("entropy algorithm") OR ((("bath algorithm") OR ("bhath algorithm"))))) OR ("el algoritmo"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"entropy algorithm\") OR (((\"bath algorithm\") OR (\"bhath algorithm\"))))) OR (\"el algoritmo\"))".
• Removing quotes may allow a broader search: (((( entropy algorithm ) OR ((( bath algorithm ) OR ( bhath algorithm ))))) OR ( el algoritmo )).
• Adding a wildcard symbol may retrieve word variants: (((("entropy algorithm") OR ((("bath algorithm") OR ("bhath algorithm"))))) OR ("el algoritmo"))*.
