Perhaps you should try some spelling variations:
optimization algorithmss » optimization algorithms, optimisation algorithm, estimation algorithm
objective optimization » multiobjective optimization
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
invasive estimation » invasive ventilation
modified invasive » modified passive

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified invasive estimation algorithms ) OR ( modified objective optimization algorithmss ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified invasive estimation algorithms ) OR ( modified objective optimization algorithmss ))".
• Adding a wildcard symbol may retrieve word variants: (( modified invasive estimation algorithms ) OR ( modified objective optimization algorithmss ))*.
