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

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified adaptive optimized algorithms") or ("modified parameter optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified adaptive optimized algorithms") OR ("modified parameter optimisation algorithm"))*.
• Removing quotes may allow a broader search: (( modified adaptive optimized algorithms ) or ( modified parameter optimisation algorithm ))*.
