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

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

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