Perhaps you should try some spelling variations:
"modified stochastic optimization algorithm" » "modified stochastic optimization algorithms", "modified stochastic optimisation algorithm", "modified stochastic estimation algorithm"
"modified caging estimation algorithmss" » "modified caging estimation algorithms", "modified caging estimation algorithm", "modified caging optimization algorithms", "modified lighting estimation algorithmss"

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 optimization algorithm") OR ("modified caging estimation algorithmss"))~.
• Removing quotes may allow a broader search: (( modified stochastic optimization algorithm ) or ( modified caging estimation algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified stochastic optimization algorithm") or ("modified caging estimation algorithmss"))*.
