2. Sunday, 10 January 2016Edward Tsang (Copyright)2 Use The Force  Constraints brought the problem here  They also guide us to solutions  Experts will follow the lead by constraints  E.g. –Constraint propagation, learning no goods –Guided Local Search (GLS) –Guided Genetic Algorithm (GGA) –The Incentive Method (used in financial forecasting and bargaining) forecastingbargaining

3. Constraints in financial forecasting EDDIE Use constraints to reflect market expectation or risk preference 10 January 2016All Rights Reserved, Edward Tsang

4. Constraints in Bargaining The Incentive Method Use constraints to focus the search in promising areas 10 January 2016All Rights Reserved, Edward Tsang

5. Conclusions  Constraints could guide us to solutions  Forecasting: –Repeated patterns were found  Bargaining: –Evolutionary computation provides an alternative approach to approximate subgame equilibrium  In both applications, constraints-directed search is crucial 10 January 2016All Rights Reserved, Edward Tsang
