Detailed Description

class exprQuad, with constant, linear and quadratic terms

It represents an expression of the form $a_0 + \sum_{i\in I} b_i x_i + x^T Q x + \sum_{i \in J} h_i (x)$ , with $a_0 + \sum_{i\in I} b_i x_i$ an affine term, $x^T Q x$ a quadratic term, and a nonlinear sum $\sum_{i \in J} h_i (x)$ . Standardization checks possible quadratic or linear terms in the latter and includes them in the former parts.

If $h_i(x)$ is a product of two nonlinear, nonquadratic functions $h'(x)h''(x)$ , two auxiliary variables $w'=f'(x)$ and $w''=h''(x)$ are created and the product $w'w''$ is included in the quadratic part of the exprQuad. If $h(x)$ nonquadratic, nonlinear function, an auxiliary variable $w=h(x)$ is created and included in the linear part.

virtual

Compute data for $\alpha$ -convexification of a quadratic form (fills in dCoeff_ and dIndex_ for the convex underestimator)

Computes alpha coefficients for an alpha under- and overestimator of the quadratic term.

For the underestimator, dCoeffLo_ is computed such that

x^TQx + sum_i dCoeffLo_i (x_i - lb x_i)(ub x_i - x-i) is convex and underestimating (alpha_i is negative),

Regarding the overestimator, dCoeffUp_ are computed such that

x^TQx + sum_i dCoeffUp_i (x_i - lb x_i)(ub x_i - x-i) is concave and overestimating (alpha_i is positive).

If the method hasn't been called, dIndex_ will be NULL. If Q is positive semidefinite, then dCoeffLo_ will be NULL. If Q is negative semidefinite, then dCoeffUp_ will be NULL.

Return true if a convexification is there, false otherwise.

void exprQuad::quadCuts	(	expression *	w,
		OsiCuts &	cs,
		const CouenneCutGenerator *	cg
	)

method exprQuad::quadCuts

Based on the information (dIndex_, dCoeffLo_, dCoeffUp_) created/modified by alphaConvexify(), create convexification cuts for this expression.

The original constraint is :

$\eta = a_0 + a^T x + x^T Q x$

where $\eta$ is the auxiliary corresponding to this expression and $ w_j $ are the auxiliaries corresponding to the other non-linear terms contained in the expression.

The under-estimator of $ x^T Q x$ is given by

$x^T Q x + \sum \lambda_{\min,i} (x_i - l_i ) (u_i - x_i )$

and its over-estimator is given by

$x^T Q x + \sum \lambda_{\max, i} (x_i - l_i ) (u_i - x_i )$

(where $\lambda_{\min, i} = \frac{\lambda_{\min}}{w_i^2}$ , $\lambda_{\max, i} = \frac{\lambda_{\max}}{w_i^2}$ , and $w_i = u_i - l_i$ ), where $\lambda_{\max}$ ( $\lambda_{\max}$ ) is the minimum (maximum) eigenvalue of the matrix $A={\rm Diag}({\bf u} - {\bf l}) Q {\rm Diag}({\bf u} - {\bf l})$ , obtained by pre- and post-multiplying $ Q $ by the diagonal matrix whose $i$ -th element is $u_i - l_i$ .

Let $\tilde a_0(\lambda)$ , $\tilde a(\lambda)$ and $\tilde Q (\lambda)$ be

$\tilde a_0(\lambda) = a_0 - \sum_{i = 1}^n \lambda_i l_i u_i$

$\tilde a(\lambda) = a + \left[ \begin{array}{c} \lambda_1 (u_1 + l_1) \\ \vdots \\ \lambda_n (u_n + l_n) \end{array} \right],$

$\tilde Q(\lambda) = Q - \left( \begin{array}{ccc} {\lambda_1} & & 0 \\ & \ddots & \\ 0 & & \lambda_n \end{array} \right).$

The convex relaxation of the initial constraint is then given by the two constraints

$\eta \geq \tilde a_0(\lambda_{\min}) + \tilde a(\lambda_{\min})^T x + x^T \tilde Q(\lambda_{\min}) x$

$\eta \leq \tilde a_0(\lambda_{\max}) + \tilde a(\lambda_{\max})^T x + x^T \tilde Q(\lambda_{\max}) x$

The cut is computed as follow. Let $(x^*, \eta^*)$ be the solution at hand. The two outer-approximation cuts are:

$\eta \geq \tilde a_0(\lambda_{\min}) + \tilde a(\lambda_{\min})^T x + {x^*}^T \tilde Q(\lambda_{\min}) (2x - x^*)$

and

$\eta \leq \tilde a_0(\lambda_{\max}) + \tilde a(\lambda_{\max})^T x + {x^*}^T \tilde Q(\lambda_{\max}) (2x - x^*);$

grouping coefficients, we get:

${x^*}^T \tilde Q(\lambda_{\min}) x^* - \tilde a_0(\lambda_{\min}) \geq (\tilde a(\lambda_{\min}) + 2 \tilde Q(\lambda_{\min} ) x^*)^T x - \eta$

and

${x^*}^T \tilde Q(\lambda_{\max}) x^* - \tilde a_0(\lambda_{\max}) \leq (\tilde a(\lambda_{\max}) + 2 \tilde Q (\lambda_{\max}) x^* )^T x - \eta$
