STOCHASTIC OPTIMIZATION OF QUERYING DISTRIBUTED DATABASES II. SOLVING STOCHASTIC OPTIMIZATION. Authors: D. DUMITRESCU, V. VARGA. |

Abstract: General stochastic query optimization (GSQO) problem for mul- tiple join | join of p relations which are stored at p different sites | is presented. GSQO problem leads to a special kind of nonlinear programming problem (P). Problem (P) is solved by using a constructive method. A se- quence converging to the solution of the optimization problem is built. Two algorithms for solving optimization problem (P) are proposed. | |||||||
