Perhaps you should try some spelling variations:
"modified parameter optimization algorithmss" » "modified parameter optimization algorithms", "modified parameter estimation algorithms", "modified parameter estimation algorithm", "modified parameters optimization algorithmss"
"modified topology optimisation algorithm" » "modified topology optimization algorithms", "modified topology estimation algorithm", "modified topology estimation algorithms", "modified topology optimization algorithm", "modified policy optimization algorithm"

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

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