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

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