Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
staffing optimisation » staffing optimization, static optimization
evolution algorithm » solution algorithm, evolutionary algorithm, convolution algorithms
invasive evolution » invasive ventilation
modified staffing » modified caging
modified invasive » modified passive

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified staffing optimisation algorithm ) OR ( modified invasive evolution algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified staffing optimisation algorithm ) OR ( modified invasive evolution algorithm ))*.
