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

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

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