WebThere are two basic types of iterative methods: 1. Stationary methods. These are methods where the data in the equation to find ~xk+1 remains fixed; they have the general form ~xk+1 = P~xk +~c for fixed matrix P and a fixed vector ~c We call P the iteration matrix. 2. Nonstationary methods. These are methods where the data changes at each WebThe PSOR variation is obtained by taking the relevant maximum of equation (10) with the option payoff function.
