Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
solutions algorithms » solution algorithm, evolution algorithm, convolution algorithms
passive solutions » positive solutions
modified passive » modified adaptive

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified bayesian optimization algorithm ) OR ( modified passive solutions algorithms ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified bayesian optimization algorithm ) OR ( modified passive solutions algorithms ))".
• Adding a wildcard symbol may retrieve word variants: (( modified bayesian optimization algorithm ) OR ( modified passive solutions algorithms ))*.
