Solutions to deterministic and stochastic dynamic programming problems using approximation, integration, and optimization methods. Mathematical economics is the application of mathematical methods to represent theories and analyze problems in economics.By convention, these applied methods are beyond simple geometry, such as differential and integral calculus, difference and differential equations, matrix algebra, mathematical programming, and other computational methods. 510.9 484.7 667.6 484.7 484.7 406.4 458.6 917.2 458.6 458.6 458.6 0 0 0 0 0 0 0 0 761.6 679.6 652.8 734 707.2 761.6 707.2 761.6 0 0 707.2 571.2 544 544 816 816 272 Š Theory can narrow range of possibilities: S-S reduced problem to 1-D dynamic programming problem Š Computation uses theoretical analysis to construct e ﬃcient computational meth-ods: P-T papers. 29, No. Keywords: Dynamic programming, optimality, computational efficiency 1.
