On linear programming relaxations for solving polynomial programming problems

linear

تسهیلات برنامه ریزی خطی برای حل مشکلات برنامه نویسی چند جمله ای This paper studies linear programming (LP) relaxations for solving polynomial programming problems. A polynomial programming problem can be equivalently formulated as a quadratically constrained quadratic program (QCQP) by introducing new variables that represent nonlinear monomials and substituting them ...

The cognitive and cultural foundations of moral behavior

behavior

پایه های شناختی و فرهنگی رفتار اخلاقی Does moral culture contribute to the evolution of cooperation? Here, we examine individuals’ and communities’ models of what it means to be good and bad and how they correspond to corollary behavior across a variety of socioecological contexts. Our sample includes over 600 ...

Numerical determination of concrete crack width for corrosion-affected concrete structures

Numerical

تعیین عددی عرض بتنی برای سازه های بتنی مقاوم در برابر خوردگی Corrosion-induced deterioration of reinforced concrete (RC) structures results in premature failure of the RC structures. In practice concrete crack width is one of the most important criteria for the assessment of the serviceability of RC structures. It is ...
