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

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