Perhaps you should try some spelling variations:
"modified objective optimisation algorithmss" » "modified objective optimisation algorithm", "modified objective optimization algorithms", "modified objective estimation algorithms", "modified objective optimization algorithmss", "modified multiobjective optimization algorithmss"
"modified bayesian estimation algorithm" » "modified bayesian optimization algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified bayesian estimation algorithm\") OR (\"modified objective optimisation algorithmss\"))~".
• Removing quotes may allow a broader search: (( modified bayesian estimation algorithm ) OR ( modified objective optimisation algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified bayesian estimation algorithm") OR ("modified objective optimisation algorithmss"))*.
