Policy evaluation is a crucial step in many reinforcement-learning procedures, which estimates a value function that predicts states’ longterm value under a given policy. In this paper, we focus on policy evaluation with linear function approximation over a fixed dataset. We first transform the empirical policy evaluation problem into a (quadratic) convex-concave saddle point problem, and then ...

resistance literature is full of patriotism and liberalism. the resistance poet defends the aims of his hometown by his poetry weapon and applies his poem at his country’s political and social service. thus the resistance poetry contains a strong epic and national spirit. this kind of literature calls people for defending their grand ideals. tamim al-barghouti is a young palestinian famous poet...

We obtain strong coloring theorems at successors of singular cardinals from failures of certain instances of simultaneous reflection of stationary sets. Along the way, we establish new results in club-guessing and in the general theory of ideals.

In this paper, we introduce the concept of a new algebraic structure: independent UP-algebras (in short, IUP-algebras), which is UP-algebras. We also concepts IUP-subalgebras, IUP-filters, IUP-ideals, and strong IUP-ideals IUP-algebras investigate their properties relationships. Finally, discuss homomorphisms between study direct inverse images four special subsets.

Circular programming problems are a new class of convex optimization problems that include second-order cone programming problems as a special case. Alizadeh and Goldfarb [Math. Program. Ser. A 95 (2003) 3-51] introduced primal-dual path-following algorithms for solving second-order cone programming problems. In this paper, we generalize their work by using the machinery of Euclidean Jordan alg...

In recent years research has recognised that notions of body image, body image ideals and body dissatisfaction develop much earlier than was once thought. Forty-seven children (25 male; 22 female) aged between 5 and 6 years were interviewed on three occasions over 12 months regarding their perceptions of body image. The interviews revealed strong negative perceptions of fatness. However, being ...

It is well known that the standard BDDC algorithm [1] requires a strong assumption on coefficients of the model problem related to the subdomain partition to achieve a good performance. In the works by Clemense and Scheichl [2,3], a bound of condition number of FETI algorithms has been analyzed depending on the coefficient variations inside subdomains. A similar problem was also considered in t...
