Perhaps you should try some spelling variations:
"modified quadratic optimization algorithms" » "modified quadratic optimisation algorithm", "modified quadratic estimation algorithms", "modified quadratic estimation algorithm", "modified static optimization algorithms"
"modified bayesian optimized algorithm" » "modified bayesian optimized algorithms", "modified bayesian optimizer algorithms", "modified bayesian optimization algorithm"

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 optimized algorithm") or ("modified quadratic optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified bayesian optimized algorithm") OR ("modified quadratic optimization algorithms")).
• Removing quotes may allow a broader search: (( modified bayesian optimized algorithm ) or ( modified quadratic optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified bayesian optimized algorithm") or ("modified quadratic optimization algorithms"))*.
