In solving the sub-problems in the child node we share (re-use) the optimum basis information (basis list and the basis factors) of the parent node. We also apply the dual algorithm which reduces the total number of pivotal steps for reoptimization. These features also justify our choice of algorithm and vindicate the useful ‘warm start’ properties of the SSX. Integer restart heuristic. In the construction of the DCEF involving, say, 500 points we are unlikely to solve all these models to QMIP optimality.

The size of the errors reported indicate that the DCEFs obtained are very close to the corresponding MEFs. 006%) for the DCEF solved to optimality (3000) points for the Hang Seng. In order to establish the computational advantage of the integer restart heuristic, we also calculate the DCEF without starting with the previous solution vector. The integer restart heuristic finds more non-dominated points and more optimal points with a smaller mean deviation in less time. To achieve similar error and optimality results, the number of nodes to be searched in the branchand-bound (B&B) algorithm needs to be increased.

Such risk measures include the ‘expected value of loss’ from Domar and Musgrave (1944), Roy’s (1952) ‘safety first’, the ‘semi-variance’ proposed by Markowitz (1959), Value at Risk–VaR–(Morgan, 1993) and its extension Conditional VaR–CVaR– (Uryasev and Rockafellar, 1999), and Fishburn’s α – t criterion (1977). The latter not only constitutes the generalized case for the above ‘below-target’ risk measures, but it is also capable of representing the symmetric risk measures. Set against this background, a financial institution faces a second dilemma of deciding which of the two main risk metric categories symmetric or asymmetric measures of risk – represent its attitude towards risk and, therefore, should be utilized.
