Perhaps you should try some spelling variations:
"binary ph based optimization algorithm" » "binary pdm based optimization algorithm" (Expand Search), "binary pd based optimization algorithm" (Expand Search), "binary ni based optimization algorithm" (Expand Search), "binary cu based optimization algorithm" (Expand Search)
"binary simple process optimization algorithm" » "binary sample process optimization algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("binary ph based optimization algorithm") OR ("binary simple process optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"binary ph based optimization algorithm\") OR (\"binary simple process optimization algorithm\"))*".
• Removing quotes may allow a broader search: (( binary ph based optimization algorithm ) OR ( binary simple process optimization algorithm ))*.
