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 caging optimization algorithm" » "modified caging optimisation algorithm", "modified caging estimation algorithm", "modified caging estimation algorithms", "modified staffing optimization algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified stochastic optimization algorithms\") OR (\"modified caging optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( modified stochastic optimization algorithms ) OR ( modified caging optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified stochastic optimization algorithms") OR ("modified caging optimization algorithm"))*.
