Solving Travelling Thief Problems using Coordination Based Methods
In TTP, city selection and item selection decisions need close coordination since the thief's travelling speed depends on the knapsack's weight and the order of visiting cities affects the order of item collection.
Surrogate Assisted Optimisation for Travelling Thief Problems
The TSP solution (cyclic tour) is typically changed in a deterministic way, while changes to the KP solution typically involve a random search, effectively resulting in a quasi-meandering exploration of the TTP solution space.
A Cooperative Coordination Solver for Travelling Thief Problems
A thief performs a cyclic tour through a set of cities, and pursuant to a collection plan, collects a subset of items into a rented knapsack with finite capacity.
Toxicity Prediction by Multimodal Deep Learning
Prediction of toxicity levels of chemical compounds is an important issue in Quantitative Structure-Activity Relationship (QSAR) modeling.
Efficient Toxicity Prediction via Simple Features Using Shallow Neural Networks and Decision Trees
Lately, it achieved significant progress in accuracy but using a huge set of features, implementing a complex blackbox technique such as a deep neural network, and exploiting enormous computational resources.
Diversified Late Acceptance Search
The well-known Late Acceptance Hill Climbing (LAHC) search aims to overcome the main downside of traditional Hill Climbing (HC) search, which is often quickly trapped in a local optimum due to strictly accepting only non-worsening moves within each iteration.
Mixing Energy Models in Genetic Algorithms for On-Lattice Protein Structure Prediction
In this paper, we develop a genetic algorithm that mainly uses a high resolution energy model for protein structure evaluation but uses a low resolution HP energy model in focussing the search towards exploring structures that have hydrophobic cores.
A Hybrid Local Search for Simplified Protein Structure Prediction
Protein structure prediction based on Hydrophobic-Polar energy model essentially becomes searching for a conformation having a compact hydrophobic core at the center.
