Perhaps you should try some spelling variations:
"modified static optimisation algorithmsss" » "modified static optimisation algorithm", "modified static optimization algorithms", "modified static estimation algorithms", "modified static optimization algorithmsss", "modified stage optimization algorithmsss", "modified stochastic optimization algorithmsss"
"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 static optimisation algorithmsss") or ("modified parameter optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified static optimisation algorithmsss") OR ("modified parameter optimization algorithm")).
• Removing quotes may allow a broader search: (( modified static optimisation algorithmsss ) or ( modified parameter optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified static optimisation algorithmsss") or ("modified parameter optimization algorithm"))*.
