Perhaps you should try some spelling variations:
"parameter optimization algorithmssssssssssss" » "parameter optimization algorithmsssssssssssss", "parameter optimisation algorithmssssssssssss", "parameter estimation algorithmssssssssssss", "parameters optimization algorithmssssssssssss"
"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.

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