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