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