Perhaps you should try some spelling variations:
"parameters optimization algorithmssssss" » "parameters optimisation algorithm", "parameters optimisation algorithmsssss", "parameters estimation algorithmssssss", "parameters estimation algorithmsssss", "parameter optimization algorithmssssss", "parameter estimation algorithmssssss"
"allocation optimization algorithms" » "allocation optimisation algorithm", "allocation estimation algorithms", "allocation estimation algorithm", "location optimization algorithms"

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 algorithms") or ("parameters optimization algorithmssssss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("allocation optimization algorithms") OR ("parameters optimization algorithmssssss")).
• Removing quotes may allow a broader search: (( allocation optimization algorithms ) or ( parameters optimization algorithmssssss )).
• Adding a wildcard symbol may retrieve word variants: (("allocation optimization algorithms") or ("parameters optimization algorithmssssss"))*.
