Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
policy optimisation » policy optimization, topology optimization
policy simulation » device simulation, plant simulation
via simulation » a simulation, _ simulation, 3d simulation

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

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