Perhaps you should try some spelling variations:
"modified network optimization algorithms" » "modified network estimation algorithms", "modified network estimation algorithm", "modified network optimized algorithms", "certified network optimization algorithms", "defined network optimization algorithms", "modified near optimization algorithms"
"modified stochastic optimisation algorithm" » "modified stochastic optimization algorithm", "modified static optimization algorithm", "modified stochastic configuration algorithm", "modified stochastic estimation algorithm", "modified stochastic estimation 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 network optimization algorithms") OR ("modified stochastic optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( modified network optimization algorithms ) or ( modified stochastic optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified network optimization algorithms") or ("modified stochastic optimisation algorithm"))*.
