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)
"bathsshsshsssshsshsshsshsh algorithm" » "bathhsshsshsssshsshsshsshsh algorithm" (Expand Search), "batshsshsshsssshsshsshsshsh algorithm" (Expand Search), "bhathsshsshsssshsshsshsshsh 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 (\"bathsshsshsssshsshsshsshsh algorithm\"))) OR (\"error algorithm\"))~".
• Removing quotes may allow a broader search: (((( bat algorithm ) OR ( bathsshsshsssshsshsshsshsh algorithm ))) OR ( error algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("bat algorithm") OR ("bathsshsshsssshsshsshsshsh algorithm"))) OR ("error algorithm"))*.
