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

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 algorithmsssssssss") OR ("parameters optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"allocation optimization algorithmsssssssss\") OR (\"parameters optimization algorithm\"))".
• Removing quotes may allow a broader search: (( allocation optimization algorithmsssssssss ) OR ( parameters optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("allocation optimization algorithmsssssssss") OR ("parameters optimization algorithm"))*.
