Perhaps you should try some spelling variations:
"error algorithm" » "entropy algorithm" (Expand Search), "search algorithm" (Expand Search)
"bat algorithm" » "bath algorithm" (Expand Search), "bats algorithm" (Expand Search), "bhat algorithm" (Expand Search)
"batsshsshshsshsshsshsshssh algorithm" » "bathsshsshshsshsshsshsshssh algorithm" (Expand Search), "batssshsshshsshsshsshsshssh algorithm" (Expand Search), "bhatsshsshshsshsshsshsshssh algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"bat algorithm\") OR (((\"batsshsshshsshsshsshsshssh algorithm\") OR (\"error algorithm\"))))~".
• Removing quotes may allow a broader search: (( bat algorithm ) OR ((( batsshsshshsshsshsshsshssh algorithm ) OR ( error algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("bat algorithm") OR ((("batsshsshshsshsshsshsshssh algorithm") OR ("error algorithm"))))*.
