Perhaps you should try some spelling variations:
"modified stochastic evolutionary algorithm" » "modified stochastic evolution algorithm", "modified stochastic solution algorithm"
"modified parameter optimization algorithm" » "modified parameter optimization algorithms", "modified parameter optimisation algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithm"

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