Perhaps you should try some spelling variations:
"modified stochastic optimisation algorithm" » "modified stochastic optimization algorithm", "modified static optimization algorithm", "modified stochastic configuration algorithm", "modified stochastic optimization algorithms", "modified stochastic estimation algorithm", "modified stochastic estimation algorithms"
"defined network optimization algorithm" » "defined network optimization algorithms", "defined network estimation algorithm", "defined network estimation algorithms"

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