— In this paper, we investigate the mathematical properties of generalized policy iteration (GPI) applied to a class of continuous-time linear systems with unknown internal dynamics. GPI is a class of dynamic programming method to solve a optimal control problem by using two consecutive steps—policy evaluation and policy improvement. We first provide(More)
Chronic treatment of rats with the estrogens 17beta-estradiol or diethylstilbestrol (DES) induces pituitary tumors in Fischer 344 but not Brown-Norway or Sprague-Dawley rats. Functional loss of retinoblastoma susceptibility gene product (pRb), a major regulatory protein for the G1 to S transition of the cell cycle, has been shown in several tumors. Here we(More)
