DOI: 10.1007/s00158-020-02740-y
Abstract: In topology optimization, the bisection method is typically used for computing the Lagrange multiplier associated with a constraint. While this method is simple to implement, it leads to oscillations in the objective and could possibly… read more here.

DOI: 10.1016/j.apnum.2017.05.011
Abstract: Abstract In this paper, we discuss a new stabilized Lagrange multiplier method for finite element solution of multi-domain elliptic and parabolic initial-boundary value problems with non-matching grid across the subdomain interfaces. The proposed method is… read more here.

DOI: 10.1103/physrevd.100.125014
Abstract: The problem of eliminating divergences arising in quantum gravity is generally addressed by modifying the classical Einstein-Hilbert action. These modifications might involve the introduction of local supersymmetry, the addition of terms that are higher-order in… read more here.

DOI: 10.1109/tcsvt.2018.2873837
Abstract: In current standardized hybrid video encoders, the Lagrange multiplier determination model is a key component in rate-distortion optimization. This originated some 20 years ago based on an entropy-constrained high-rate approximation and experimental results obtained using… read more here.

DOI: 10.1109/tnet.2022.3162930
Abstract: This paper studies the localization problem using noisy range-difference measurements, or equivalently time difference of arrival (TDOA) measurements. There is a reference sensor, and for each other sensor, the TDOA measurement is obtained with respect… read more here.
