Sensitivity analysis and tailored design of minimization diagrams
Ernesto G. Birgin, Antoine Laurain, Tiago C. Menezes
Minimization diagrams encompass a large class of diagrams of interest in the literature, such as generalized Voronoi diagrams. We develop an abstract perturbation theory and perfor…
Block Coordinate Descent for smooth nonconvex constrained minimization
E. G. Birgin, J. M. Martínez
At each iteration of a Block Coordinate Descent method one minimizes an approximation of the objective function with respect to a generally small set of variables subject to constr…
Relax-and-fix heuristics applied to a real-world lot-sizing and scheduling problem in the personal care consumer goods industry
K. A. G. Araujo, E. G. Birgin, M. S. Kawamura +1
This paper addresses an integrated lot-sizing and scheduling problem in the industry of consumer goods for personal care, a very competitive market in which the good customer servi…
A forward-looking matheuristic approach for the multi-period two-dimensional non-guillotine cutting stock problem with usable leftovers
E. G. Birgin, O. C Romão, D. P. Ronconi
In [E. G. Birgin, O. C. Romão, and D. P. Ronconi, The multi-period two-dimensional non-guillotine cutting stock problem with usable leftovers, International Transactions in Operati…
A Shape-Newton approach to the problem of covering with identical balls
Ernesto G. Birgin, Antoine Laurain, Rafael Massambone +1
The problem of covering a region of the plane with a fixed number of minimum-radius identical balls is studied in the present work. An explicit construction of bi-Lipschitz mapping…
Accelerated derivative-free spectral residual method for nonlinear systems of equations
Ernesto G. Birgin, John L. Gardenghi, Diaulas S. Marcondes +1
Spectral residual methods are powerful tools for solving nonlinear systems of equations without derivatives. In a recent paper, it was shown that an acceleration technique based on…
Accelerated derivative-free nonlinear least-squares applied to the estimation of Manning coefficients
E. G. Birgin, J. M. Martínez
A general framework for solving nonlinear least squares problems without the employment of derivatives is proposed in the present paper together with a new general global convergen…
