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