Perhaps you should try some spelling variations:
"parameter optimization algorithmsssssssssss" » "parameter optimization algorithmssssssssssss", "parameter optimisation algorithmsssssssssss", "parameter estimation algorithmsssssssssss", "parameters optimization algorithmsssssssssss"
"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 algorithmsssssssssss") OR ("allocation optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"parameter optimization algorithmsssssssssss\") OR (\"allocation optimization algorithm\"))".
• Removing quotes may allow a broader search: (( parameter optimization algorithmsssssssssss ) OR ( allocation optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("parameter optimization algorithmsssssssssss") OR ("allocation optimization algorithm"))*.
