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

You may be able to get more results by adjusting your search query.

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