Perhaps you should try some spelling variations:
"modified objective allocation algorithms" » "modified objective estimation algorithms", "modified objective approximation algorithms"
"modified stochastic evolution algorithm" » "modified stochastic solution algorithm", "modified stochastic evolutionary algorithm", "modified stochastic convolution algorithms"

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 stochastic evolution algorithm") OR ("modified objective allocation algorithms"))~.
• Removing quotes may allow a broader search: (( modified stochastic evolution algorithm ) or ( modified objective allocation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified stochastic evolution algorithm") or ("modified objective allocation algorithms"))*.
