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)
"bathhhsssh algorithm" » "bathhhhsssh algorithm" (Expand Search), "batshhhsssh algorithm" (Expand Search), "bhathhhsssh algorithm" (Expand Search), "bathhhsssh algoritmo" (Expand Search)
"bathhhhhsshsshsshsshssh algorithm" » "bathhhhhhsshsshsshsshssh algorithm" (Expand Search), "batshhhhhsshsshsshsshssh algorithm" (Expand Search), "bhathhhhhsshsshsshsshssh algorithm" (Expand Search), "bathhhhhsshsshsshsshssh 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 (((\"bathhhsssh algorithm\") OR (\"bathhhhhsshsshsshsshssh algorithm\"))))~".
• Removing quotes may allow a broader search: (( bat algorithm ) OR ((( bathhhsssh algorithm ) OR ( bathhhhhsshsshsshsshssh algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("bat algorithm") OR ((("bathhhsssh algorithm") OR ("bathhhhhsshsshsshsshssh algorithm"))))*.
