This activity plan proposes the application of optimization techniques to the Molecular Distance Geometry Problem, focusing on the determination of the three-dimensional structure of proteins. The research seeks to overcome limitations of the reference method in the literature, the "Symmetry-based Build-up," through a hybrid approach that combines the discrete structure of partial reflect…
This project deals with theoretical, computational and application aspects of Optimization. The project aims at the development, theoretical analysis, implementation and application of algorithms for different aspects of Optimization, with emphasis on Continuous Optimization. The project relies on applications with which the team is familiar. Emphasis is placed on algorithms with a solid …
This activity plan focuses on applying continuous optimization techniques to two contexts: hyperparameter tuning in machine learning and distance geometry, specifically in describing the 3D structure of proteins, both of which have significant optimization applications. In addition to theoretical foundations, this project aims to develop and provide computational codes useful to the acade…

The calculation of the 3D structure of a protein molecule, using distances between nearby atoms from Nuclear Magnetic Resonance (NMR) experiments, is a fundamental problem related to the complex and costly process of development of new drugs by the pharmaceutical industry. The problem is NP-difficult, known in the literature by Molecular Distance Geometry Problem (MDGP). Unlike traditiona…

The intersection of spheres plays a central role in the combinatorial model of the Molecular Distance Geometry Problem (MDGP), a classical formulation of the problem of determining molecular structures from exact distance data. However, when the distances provided by Nuclear Magnetic Resonance (NMR) experiments are represented as intervals, it becomes necessary to consider intersections o…
The field of structural biology has made significant progress in determining protein structures, which is crucial for understanding their biological functions and molecular activities, with important implications for health and biotechnology. Over the past decades, this area has produced numerous protein structures, primarily using continuous optimization approaches and local techniques. …

The problem is the calculation of the 3D structure of a protein molecule using distances between close atoms from Nuclear Magnetic Resonance (NMR) experiments. This is a fundamental problem in the complex and costly process of new drug development by the pharmaceutical industry. It is an NP-hard problem, known in the literature as Molecular Distance Geometry Problem (MDGP). Unlike traditi…
The Molecular Distance Geometry Problem (MDGP) is the problem of finding the conformation of a molecule from inter-atomic distances. In some recent work, we proposed the Branch and Prune (BP) algorithm that was developed based on artificial instances of the MDGP, which allows the discretization of the problem, and hence the applicability of the BP algorithm. The algorithm explores a discr…
