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)
"batsshsshsshsshsssshsshsshsshsh algorithm" » "bathsshsshsshsshsssshsshsshsshsh algorithm" (Expand Search), "batssshsshsshsshsssshsshsshsshsh algorithm" (Expand Search), "bhatsshsshsshsshsssshsshsshsshsh 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 (\"batsshsshsshsshsssshsshsshsshsh algorithm\"))) OR (\"error algorithm\"))~".
• Removing quotes may allow a broader search: (((( bat algorithm ) OR ( batsshsshsshsshsssshsshsshsshsh algorithm ))) OR ( error algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("bat algorithm") OR ("batsshsshsshsshsssshsshsshsshsh algorithm"))) OR ("error algorithm"))*.
