Sheet-metal press line parameter tuning using a combined DIRECT and Nelder-Mead algorithm [PDF]
, 2011 It is a great challenge to obtain an efficient algorithm for global optimisation of nonlinear, nonconvex and high dimensional objective functions. This paper shows how the combination of DIRECT and Nelder-Mead algorithms can improve the efficiency in the

Algorithm for efficient symbolic analysis of large analogue circuits [PDF]
, 1994 An algorithm is presented that generates simplified symbolic expressions for the small-signal characteristics of large analogue circuits. The expressions are approximated while they are computed, so that only the most significant terms are generated ...

A simple, fast, and accurate algorithm to estimate large phylogenies by maximum likelihood.
Systematic Biology, 2003 The increase in the number of large data sets and the complexity of current probabilistic sequence evolution models necessitates fast and reliable phylogeny reconstruction methods.

A novel swarm intelligence optimization approach: sparrow search algorithm
, 2020 In this paper, a novel swarm optimization approach, namely sparrow search algorithm (SSA), is proposed inspired by the group wisdom, foraging and anti-predation behaviours of sparrows.

IQ-TREE: A Fast and Effective Stochastic Algorithm for Estimating Maximum-Likelihood Phylogenies
Molecular biology and evolution, 2014 Large phylogenomics data sets require fast tree inference methods, especially for maximum-likelihood (ML) phylogenies. Fast programs exist, but due to inherent heuristics to find optimal trees, it is not clear whether the best tree is found.

Arc-Search Infeasible Interior-Point Algorithm for Linear Programming [PDF]
Numerical Algorithms (2017) 74:(4) 967-996, 2014 Mehrotra's algorithm has been the most successful infeasible interior-point algorithm for linear programming since 1990. Most popular interior-point software packages for linear programming are based on Mehrotra's algorithm. This paper proposes an alternative algorithm, arc-search infeasible interior-point algorithm.
