Perhaps you should try some spelling variations:
probes optimization » process optimization (Expand Search), robust optimization (Expand Search), property optimization (Expand Search)
based optimization » whale optimization (Expand Search)
laboratory based » laboratory values (Expand Search), laboratory data (Expand Search), laboratory tests (Expand Search)
based probes » based protein (Expand Search)
mod based » model based (Expand Search), food based (Expand Search), wood 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: (( laboratory based probes optimization algorithm ) OR ( binary mod based optimization algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( laboratory based probes optimization algorithm ) OR ( binary mod based optimization algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( laboratory based probes optimization algorithm ) OR ( binary mod based optimization algorithm ))*.
