Perhaps you should try some spelling variations:
optimisation algorithms » optimization algorithms, estimation algorithms, estimation algorithm
parameter optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
changing optimisation » staffing optimization
modified changing » modified caging

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified parameter optimisation algorithm ) OR ( modified changing optimisation algorithms ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified parameter optimisation algorithm ) OR ( modified changing optimisation algorithms ))*".
