We show that among connected graphs with maximum clique size <img src="/cgi-bin/mimetex.cgi?\omega">, the minimum value of the spectral radius of adjacency m...

We present and compare three new compact linearizations for the quadratic 0-1 minimization problem, two of which achieving the same lower bound than the "sta...

Data clustering methods have been developed extensively in the data mining literature for detecting useful patterns in large datasets in the form of dense...

The <i>Capacitated Arc Routing Problem</i> (CARP) consists of determining a set of least cost capacitated vehicle routes servicing a set of arcs. In this p...

We consider a noncooperative differential game where a retailer sells her own private label in addition to the manufacturer’s brand. We assume that each bran...

A set of vertices <i>S</i> in a graph <i>G</i> is a clique if any two of its vertices are adjacent. The clique number <img src="/cgi-bin/mimetex.cgi?\omega"...

In this paper we study the Capacitated Team Orienteering and Profitable Tour Problems (CTOP and CPTP). The interest in these problems comes from recent devel...

In this survey, we examine an important class of facility location problems known as the multisource Weber problem (also referred to as the continuous locat...

A recent comparison of evolutionary, neural network, and scatter search heuristics for solving the p-median problem is completed by (i) gathering or obtaini...

An edge coloring of a graph <img src="/cgi-bin/mimetex.cgi?G = (V,E)"> is a function <img src="/cgi-bin/mimetex.cgi?c:E \rightarrow N"> that assigns a co...

We consider the problem of assigning patients to nurses for home care services. The aim is to balance the workload of the nurses while avoiding long travels...

The probabilistic satisfiability problem is to verify the consistency of a set of probability values or intervals for logical propositions. The (tight) prob...

In One-to-Many-to-One Single Vehicle Pickup and Delivery Problems a vehicle based at the depot must make deliveries and pickups at customers locations befor...

A set of vertices <i>S</i> in a graph <i>G</i> is independent if no neighbor of a vertex of <i>S</i> belongs to <i>S</i>. A set of vertices <i>U</i> in a gr...

In modern transportation systems, the potential for further decreasing the costs of fulfilling customer requests is severely limited while market competitio...

The AutoGraphiX 2 system is used to compare the index of a graph <i>G</i> with a number of other graph theoretical invariants, i.e., chromatic number, maxim...

Assouad has shown that a real-valued distance <i>d</i> = (<i>d</i>_<i>ij</i>) _{1 &le; <i>i</i> &lt; <i>j</i> &le; <i>n</i>} is isome...

The <i>Dial-a-Ride Problem</i> (DARP) consists of designing vehicle routes and schedules for <i>n</i> users who specify pickup and delivery requests between...

In one-to-one <i>Pickup and Delivery Problems</i> (PDPs), the aim is to design a set of least cost vehicle routes starting and ending at a common depot in o...

We consider a marketing channel where a retailer sells, along the manufacturer’s brand, her own private label. We assume that each player invests in adverti...
