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