Perhaps you should try some spelling variations:
"attributed optimization algorithm" » "attribute optimization algorithm", "attributed optimisation algorithm", "attributed estimation algorithm", "attributed estimation algorithms"
"parameters optimization algorithms" » "parameter optimization algorithms", "parameter estimation algorithms", "parameters optimisation algorithm", "parameters estimation algorithms", "parameters estimation algorithm", "parameters optimisation algorithms", "parameters estimation algorithmss"

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

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