#### A genuinely polynomial primal simplex algorithm for the assignment problem

(Elsevier, 1993)

We present a primal simplex algorithm that solves the assignment problem in 1 2n(n+3)-4 pivots. Starting with a problem of size 1, we sequentially solve problems of size 2,3,4,...,n. The algorithm utilizes degeneracy by ...

#### Solving school bus routing problems through integer programming

(Palgrave Macmillan Ltd., 2007)

In this paper, an exact solution approach is described for solving a real-life school bus routing problem (SBRP) for transporting the students of an elementary school throughout central Ankara, Turkey. The problem is ...

#### Pricing multiple exercise American options by linear programming

(Springer New York LLC, 2017)

We consider the problem of computing the lower hedging price of American options of the call and put type written on a non-dividend paying stock in a non-recombinant tree model with multiple exercise rights. We prove using ...

#### A global error bound for quadratic perturbation of linear programs

(Elsevier, 2002)

We prove a global error bound result on the quadratic perturbation of linear programs. The error bound is stated in terms of function values.

#### A characterization of the optimal set of linear programs based on the augmented lagrangian

(Taylor & Francis, 1999)

It is proved that in a certain neighborhood of the optimal set of multipliers, the set of minimizers of the augmented lagrangian nmction generates a new characterization of the optimal solution set of the linear program.

#### A new finite continuation algorithm for linear programming

(Society for Industrial and Applied Mathematics, 1996)

We describe a new finite continuation algorithm for linear programming. The dual of the linear programming problem with unit lower and upper bounds is formulated as an f\ minimization problem augmented with the addition ...

#### Escaping local optima in a class of multi-agent distributed optimization problems: a boosting function approach

(IEEE, 2014)

We address the problem of multiple local optima commonly arising in optimization problems for multi-agent systems, where objective functions are nonlinear and nonconvex. For the class of coverage control problems, we propose ...

#### Formulations and valid inequalities for the heterogeneous vehicle routing problem

(Springer, 2006)

We consider the vehicle routing problem where one can choose among vehicles with different costs and capacities to serve the trips. We develop six different formulations: the first four based on Miller-Tucker-Zemlin ...

#### Hub location under competition

(Elsevier, 2016)

Hubs are consolidation and dissemination points in many-to-many flow networks. Hub location problem is to
locate hubs among available nodes and allocate non-hub nodes to these hubs. The mainstream hub location
studies ...

#### Scheduling with tool changes to minimize total completion time: a study of heuristics and their performance

(John Wiley & Sons, Inc., 2003)

The machine scheduling literature does not consider the issue of tool change. The
parallel literature on tool management addresses this issue but assumes that the change is due
only to part mix. In practice, however, a ...
