We give an algorithm determining whether a hermiticity-preserving superoperator is positive. In our approach we apply techniques of quantifier elimination theory for real numbers. Furthermore, we ...

Abstract: A method based on a quantifier elimination algorithm is suggested for obtaining explicit model predictive control (MPC) laws for linear time invariant systems with quadratic objective and ...

Cylindrical Algebraic Decomposition (CAD) is a pivotal algorithmic technique in real algebraic geometry, instrumental in resolving problems expressed in a first‐order language over the reals. By ...

#TSG2014冬学期QE分科会 QE(Quantifier Elimination、限量記号消去)のアルゴリズム、特にCAD法について、実例を多く挙げて分かりやすくし、かつ自分の理解の及ぶ限り理論的側面を重視した説明にすることを目標にする。理解不十分による間違いが含まれていることも ...

Quantum communication channels suffer from various noises, which are mathematically modeled by error super-operators. To combat these errors, it is necessary to ...

Implementation of quantifier elimination for bit vector arithmetic based on elimination of quantifiers for Presburger arithmetic expanded by function 2^x (in progress).

The Journal of Symbolic Logic (JSL) was founded in 1936 and it has become the leading research journal in the field. It is issued quarterly. Volume 71, being published during 2006, will consist of ...

Automated synthesis of program fragments from specifications can make programs easier to write and easier to reason about. To integrate synthesis into programming languages, software synthesis ...
