Hamiltonian path planning in constrained workspace [PDF]
European Journal of Control, 2017 Abstract A methodology to plan the trajectories of robots that move in an n-dimensional Euclidean space, have to reach a target avoiding obstacles and are constrained to move in a region of the space is described. It is shown that if the positions of the obstacles are known then a Hamiltonian function can be constructed and used to define a collision ...

Hamilton-chain saturated hypergraphs [PDF]
, 2010 We say that a hypergraph H is hamiltonian path (cycle) saturated if H does not contain an open (closed) hamiltonian chain but by adding any new edge we create an open (closed) hamiltonian chain in H.

Solving a Hamiltonian Path Problem with a bacterial computer
Journal of Biological Engineering, 2009 Background The Hamiltonian Path Problem asks whether there is a route in a directed graph from a beginning node to an ending node, visiting each node exactly once. The Hamiltonian Path Problem is NP complete, achieving surprising computational complexity

Advanced Engineering Materials, EarlyView.The utilization of direct energy deposition (DED)‐arc additive manufacturing processes in industrial applications is increasing, and these processes have the potential for multi‐material applications. This work provides a overview of the state of research in DED‐arc made functional graded structures, to establish a link to potential industrial ...

Chain level Floer theory and Hofer's geometry of the Hamiltonian diffeomorphism group
, 2001 In this paper we first apply the chain level Floer theory to the study of Hofer's geometry of Hamiltonian diffeomorphism group in the cases without quantum contribution: we prove that any quasi-autonomous Hamiltonian path on weakly exact symplectic ...

The Hamiltonian limit of (3+1)D SU(3) lattice gauge theory on anisotropic lattices [PDF]
, 2003 The extreme anisotropic limit of Euclidean SU(3) lattice gauge theory is examined to extract the Hamiltonian limit, using standard path integral Monte Carlo (PIMC) methods.

Path Independence in Adiabatic Quantum Computing for Hadamard Gate
Journal of Mathematical and Fundamental Sciences, 2014 The computation time in adiabatic quantum computing (AQC) is determined by the time limit of the adiabatic evolution, which in turn depends on the evolution path. In this research we have used the variational method to find an optimized path.
