Perhaps you should try some spelling variations:
"entropy algorithm" » "error algorithm" (Expand Search)
"bat algorithm" » "bath algorithm" (Expand Search), "bats algorithm" (Expand Search), "bhat algorithm" (Expand Search)
"batsshshshsshsshshhhsshssssh algorithm" » "bathsshshshsshsshshhhsshssssh algorithm" (Expand Search), "batssshshshsshsshshhhsshssssh algorithm" (Expand Search), "bhatsshshshsshsshshhhsshssssh 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 (\"entropy algorithm\"))) OR (\"batsshshshsshsshshhhsshssssh algorithm\"))~".
• Removing quotes may allow a broader search: (((( bat algorithm ) OR ( entropy algorithm ))) OR ( batsshshshsshsshshhhsshssssh algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("bat algorithm") OR ("entropy algorithm"))) OR ("batsshshshsshsshshhhsshssssh algorithm"))*.
