Perhaps you should try some spelling variations:
"modified bayesian optimisation algorithms" » "modified bayesian optimisation algorithm", "modified bayesian estimation algorithms", "modified bayesian estimation algorithm", "modified bayesian optimization algorithms"
"modified lighting optimization algorithms" » "modified lighting optimisation algorithm", "modified lighting estimation algorithms", "modified lighting estimation algorithm", "modified staffing optimization algorithms", "modified caging optimization algorithms"

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

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