Perhaps you should try some spelling variations:
"bat algorithm" » "bath algorithm" (Expand Search), "bats algorithm" (Expand Search), "bhat algorithm" (Expand Search), "bat algoritmo" (Expand Search)
"bathsssshsssh algorithm" » "bathhsssshsssh algorithm" (Expand Search), "batshsssshsssh algorithm" (Expand Search), "bhathsssshsssh algorithm" (Expand Search), "bathsssshsssh algoritmo" (Expand Search)
"bhatsshshsshsshssh algorithm" » "bhatsshshsshsshssh algoritmo" (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 (((\"bathsssshsssh algorithm\") OR (\"bhatsshshsshsshssh algorithm\"))))~".
• Removing quotes may allow a broader search: (( bat algorithm ) OR ((( bathsssshsssh algorithm ) OR ( bhatsshshsshsshssh algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("bat algorithm") OR ((("bathsssshsssh algorithm") OR ("bhatsshshsshsshssh algorithm"))))*.
