Perhaps you should try some spelling variations:
"modified parameters optimization algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithms", "modified parameters estimation algorithm", "modified parameters estimation algorithms"
"modified changing optimisation algorithm" » "modified changing optimization algorithms", "modified changing estimation algorithm", "modified changing estimation algorithms", "modified staffing optimization algorithm", "modified caging optimisation algorithm"

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

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