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"
"topology optimisation algorithm" » "topology optimization algorithms", "topology estimation algorithm", "topology estimation algorithms", "topology optimization algorithm", "policy optimization algorithm"

Try widening your search to All Fields.

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