Figure 2: This figure represents the generalized efficient frontier for a portfolio ma<strong>de</strong> of seventeen risky<br />

ass<strong>et</strong>s. The optimiz<strong>at</strong>ion problem is solved numerically, using a gen<strong>et</strong>ic algorithm, with risk measures given<br />

respectively by the centered moments µ2, µ4, µ6 and µ8. The straight lines are the efficient frontiers when<br />

we add to these ass<strong>et</strong>s a risk-free ass<strong>et</strong> whose interest r<strong>at</strong>e is s<strong>et</strong> to 5% a year.<br />
