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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("parameters optimisation algorithmss") or ("allocation optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("parameters optimisation algorithmss") OR ("allocation optimisation algorithm")).
• Removing quotes may allow a broader search: (( parameters optimisation algorithmss ) or ( allocation optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("parameters optimisation algorithmss") or ("allocation optimisation algorithm"))*.
