Perhaps you should try some spelling variations:
"modified policy estimation algorithms" » "modified policy estimation algorithm", "modified policy optimization algorithms", "modified policy optimisation algorithm", "modified pose estimation algorithms", "modified motion estimation 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.

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