摘　　要：针对离散极大极小函数综合是一类特殊的不可微最优化问题，提出了用可微最优化问题来逼近它的基本算法。为克服逼近问题的某些不良性质和状态，提出了非单调曲线搜索算法。应用上述算法构造了一种极大极小函数综合的求解方法，并在很弱的条件下得到了算法的收敛性。该方法具有算法简单。By using differential problem to approximate the discrete minimax function synthesis which is a kind of special nondifferentiable optimization problem, a basic algorithm is presented To overcome some ill - conditioned properties of the approximating problem, a nonttonotote curvilinear search algo rithm is given . Using the algorithms ahove an approach for solving constrained minimax function synthesis is constructed and under wea ker conditions the convergence of the approch is obtained . The approach is simpler in form, easily used and has higher accuracy in computation .
