Constraint summation in phonological theory

open access: yesJournal of Language Modelling, 2021
The classical constraints used in phonological theory apply to a single candidate at a time. Yet, some proposals in the phonological literature have enriched the classical constraint toolkit with constraints that instead apply to multiple candidates ...

Theory and Practice of Constraint Handling Rules

open access: yesThe Journal of Logic Programming, 1998
Summary: Constraint Handling Rules (CHR) are our proposal to allow more flexibility and application-oriented customization of constraint systems. CHR are a declarative language extension especially designed for writing user-defined constraints. CHR are essentially a committed-choice language consisting of multi-headed guarded rules that rewrite ...

Theory-guided hard constraint projection (HCP): a knowledge-based data-driven scientific machine learning method [PDF]

open access: yesJournal of Computational Physics, 2020
Machine learning models have been successfully used in many scientific and engineering fields. However, it remains difficult for a model to simultaneously utilize domain knowledge and experimental observation data.

A Review on Constraint Handling Techniques for Population-based Algorithms: from single-objective to multi-objective optimization [PDF]

open access: yesArchives of Computational Methods in Engineering, 2022
Most real-world problems involve some type of optimization problems that are often constrained. Numerous researchers have investigated several techniques to deal with constrained single-objective and multi-objective evolutionary optimization in many ...

The resources occupancy in resource – constrained multi project scheduling problem [PDF]

open access: yesComputer Methods in Materials Science, 2011
This paper presents an adaptation of the Theory of Constraint (TOC ) to the multi – project scheduling problem. Variables customer expectations have forced changes in the company management.

Field Theories for type-II fractons

open access: yesSciPost Physics, 2022
We derive an effective field theory for a type-II fracton starting from the Haah code on the lattice. The effective topological theory is not given exclusively in terms of an action; it must be supplemented with a condition that selects physical ...

Improving Nutrition Services to Reduce Plate Waste in Patients Hospitalized Based on Theory of Constraint

open access: yesAmerta Nutrition, 2020
Background: Highly plate waste in hospitalized patients has become a problem in Hospitals’ nutrition service department, this causes adding treatment time for patient’s recovery and making the hospital service inefficient.

Light-by-Light Scattering Constraint on Born-Infeld Theory. [PDF]

open access: yesPhysical Review Letters, 2017
The recent measurement by ATLAS of light-by-light scattering in LHC Pb-Pb collisions is the first direct evidence for this basic process. We find that it excludes a range of the mass scale of a nonlinear Born-Infeld extension of QED that is ≲100  GeV, a ...

Revision to Theory of Constraints [PDF]

open access: yes, 2010
It's intended to give an approximation to the Theory of Constraints (TOC), to achieve that goal we explain the conceptual bases, the thinking process, the flow management and later on we will focus on its application into production, also known as DBR (Drum-Buffer-Rope).
