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

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