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