Detailed Description

Simionescu constrained test problem.

• Number of parameters: 2
• Number of inequality constraints: 1
• Number of equality constraints: 0
• Domain: \(\bar{\vec{x}} \in [-5/4, 5/4]^2\)
• Optimal point: \(\bar{\vec{x}}_{\text{opt}} = 3\sqrt{2}/5 \cdot (\pm 1, \mp 1)\)
• Optimal function value: \(\bar{f}(\bar{\vec{x}}_{\text{opt}}) = -9/125\)
