Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
changing optimisation » staffing optimization
ventilation algorithm » estimation algorithm, estimation algorithms, evolution algorithm
passive ventilation » adaptive ventilation, invasive ventilation
modified changing » modified caging
modified passive » modified adaptive

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

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