Perhaps you should try some spelling variations:
"modified stochastic optimization algorithm" » "modified stochastic optimization algorithms", "modified stochastic optimisation algorithm", "modified stochastic estimation algorithm"
"modified pose estimation algorithms" » "modified pose estimation algorithm", "modified pose optimization algorithms", "modified pose optimisation algorithm", "modified male estimation algorithms", "modified passive estimation 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 optimization algorithm") OR ("modified pose estimation algorithms"))~.
• Removing quotes may allow a broader search: (( modified stochastic optimization algorithm ) or ( modified pose estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified stochastic optimization algorithm") or ("modified pose estimation algorithms"))*.
