Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm
estimation algorithms » estimation algorithm, optimization algorithms, approximation algorithms
simulation algorithm » estimation algorithm, solution algorithm, evolution algorithm
plant simulation » policy simulation, a simulation, via simulation

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( pose ((optimisation algorithm) OR (estimation algorithms)) ) or ( plant simulation algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( pose ((optimisation algorithm) OR (estimation algorithms)) ) OR ( plant simulation algorithm ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( pose ((optimisation algorithm) OR (estimation algorithms)) ) or ( plant simulation algorithm ))*".
