Perhaps you should try some spelling variations:
"modified parameter optimization algorithm" » "modified parameter optimization algorithms", "modified parameter optimisation algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithm"
"modified stochastic optimizer algorithmss" » "modified stochastic optimizer algorithms", "modified stochastic optimized algorithms", "modified stochastic optimized algorithm", "modified stochastic optimization algorithmss"

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