Conditional observability
For a quantum Hamiltonian H = H(λ), the observability of the energies E may be robust (whenever all E are real at all λ) or, otherwise, conditional. Using a pseudoHermitian family of N−state chain models H = H(λ) we discuss some generic properties of conditionally observable spectra.
متن کاملComplexity of Conditional Planning under Partial Observability and Infinite Executions
The computational properties of many classes of conditional and contingent planning are well known. The main division in the field is between probabilistic planning (typically infinite or unbounded executions, reward rather than goal-based, and focus on expected costs or rewards) and non-probabilistic planning (ignoring probabilities, focus on plans that reach goal states.) In this work, we add...
متن کاملConditional observability versus self-duality in a schematic model
For a 4-dimensional 3-parametric toy Hamiltonian H(a, b, c) we construct the domain D of couplings in which the eigenvalues En remain real (i.e., in principle, observable). A relationship is found between the reflection symmetry of the spectrum (i.e., its Dunne’s and Shifman’s self-duality Ej = −EN+1−j at N = 4) and a geometric symmetry of the physical domain D. Simultaneously, both remain unbr...
متن کاملConditional Planning under Partial Observability as Heuristic-Symbolic Search in Belief Space
Planning under partial observability in nondeterministic domains is a very significant and challenging problem, which requires dealing with uncertainty together with and-or search. In this paper, we propose a new algorithm for tackling this problem, able to generate conditional plans that are guaranteed to achieve the goal despite of the uncertainty in the initial condition and the uncertain ef...
متن کاملFormulae relating controllability, observability, and co-observability
We present formulae relating controllability, observability, and co-observability arising in the context of supervisory control of discrete event systems. Given a discrete event plant G with event set Σ, uncontrollable event set Σui, and observation mask Mi of the ith supervisor, we first show that the infimal prefix-closed, (L(G), ⋂ i Σui)controllable, and (L(G),Σui,Mi)–co-observable superlang...
