Perhaps you should try some spelling variations:
"modified adaptive evolutionary algorithm" » "modified adaptive evolution algorithm", "modified adaptive solution algorithm", "modified objective evolutionary algorithm", "modified passive evolutionary algorithm"
"modified bayesian optimization algorithm" » "modified bayesian optimization algorithms", "modified bayesian optimisation algorithm", "modified bayesian estimation algorithm"

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified adaptive evolutionary algorithm") or ("modified bayesian optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified adaptive evolutionary algorithm") OR ("modified bayesian optimization algorithm")).
• Removing quotes may allow a broader search: (( modified adaptive evolutionary algorithm ) or ( modified bayesian optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive evolutionary algorithm") or ("modified bayesian optimization algorithm"))*.
