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 algorithmss" » "modified pose estimation algorithms", "modified pose estimation algorithm", "modified pose optimization algorithms", "modified male estimation algorithmss", "modified passive estimation algorithmss"

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified stochastic optimization algorithm") or ("modified pose estimation algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified stochastic optimization algorithm") OR ("modified pose estimation algorithmss")).
• Removing quotes may allow a broader search: (( modified stochastic optimization algorithm ) or ( modified pose estimation algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified stochastic optimization algorithm") or ("modified pose estimation algorithmss"))*.
