Perhaps you should try some spelling variations:
process optimization » model optimization (Expand Search)
based optimization » whale optimization (Expand Search)
day process » dual process (Expand Search), key process (Expand Search), a process (Expand Search)
binary day » binary data (Expand Search)
ptv based » ppv based (Expand Search), uav based (Expand Search), hiv based (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 ptv based optimization algorithm ) OR ( binary day process optimization algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( binary ptv based optimization algorithm ) OR ( binary day process optimization algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( binary ptv based optimization algorithm ) OR ( binary day process optimization algorithm ))*.
