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