Minimizing the Height of Simple Tangles

open access: yesJournal of Graph Algorithms and Applications
A tangle $T$ of height $h$ describes the ordering of $n$ elements called wires on each of $h$ levels. A pair of wires $ab$ is called a swap. Between any two adjacent levels only the ordering of adjacent wires may swap and each wire may participate in ...

Evaluating the Effects of the Clique Selection in Exact Graph Coloring Algorithms

open access: yes, 2011
It is a common practice in exact enumerative algorithms for graph colouring to find a clique of maximum cardinality and to fix the colours of this subgraph before proceeding with implicit enumeration on the remainder of the graph.

An Algorithm for Exact Division

open access: yesJournal of Symbolic Computation, 1993
Division of long integers is a frequently performed task in computer algebra. The common algorithms used for that purpose rely on computing quotient and remainder (IQR), even when it is known in advance that the latter one is zero. The author proposes to exploit the fact that the division is exact and gives a time-saving algorithm (EDIV) starting from ...

Exact and Heuristic Algorithms for Thrift Cyclic Scheduling

open access: yesAlgorithms, 2009
Non-preemptive schedulers, despite their many discussed drawbacks, remain a very popular choice for practitioners of real-time and embedded systems. The non-preemptive ‘thrift’ cyclic scheduler—variations of which can be found in other application areas ...

Exact algorithms for the rectilinear block packing problem

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2018
The rectilinear block packing problem is a problem of packing a set of rectilinear blocks into a larger rectangular container with fixed width and unrestricted height. A rectilinear block is a polygonal block whose interior angles are either 90◦ or 270◦.

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.
