Beam Nested Rollout Policy Adaptation
The Nested Rollout Policy Adaptation algorithm is a tree search algorithm known to be efficient on combinatorial problems. However, one problem of this algorithm is that it can converge to a local optimum and get stuck in it. We propose a modification which limits this behavior and we experiment it on two combinatorial problems for which the Nested Rollout Policy Adaption is known to be good at.
متن کاملImproved Diversity in Nested Rollout Policy Adaptation
For combinatorial search in single-player games nested MonteCarlo search is an apparent alternative to algorithms like UCT that are applied in two-player and general games. To trade exploration with exploitation the randomized search procedure intensifies the search with increasing recursion depth. If a concise mapping from states to actions is available, the integration of policy learning yiel...
متن کاملNested Rollout Policy Adaptation with Selective Policies
Monte Carlo Tree Search (MCTS) is a general search algorithm that has improved the state of the art for multiple games and optimization problems. Nested Rollout Policy Adaptation (NRPA) is an MCTS variant that has found record-breaking solutions for puzzles and optimization problems. It learns a playout policy online that dynamically adapts the playouts to the problem at hand. We propose to enh...
متن کاملApoptosis: from Signalling Pathways to Therapeutic Tools
Apoptosis or programmed cell death is a gene regulated phenomenon which is important in both physiological and pathological conditions. It is characterized by distinct morphological features including chromatin condensation, cell and nuclear shrinkage, membrane blebbing and oligonucleosomal DNA fragmentation. Although, two major apoptotic pathways including 1) the death receptor (extrinsic) and...
متن کاملAdaptation to High Ethanol Reveals Complex Evolutionary Pathways
Tolerance to high levels of ethanol is an ecologically and industrially relevant phenotype of microbes, but the molecular mechanisms underlying this complex trait remain largely unknown. Here, we use long-term experimental evolution of isogenic yeast populations of different initial ploidy to study adaptation to increasing levels of ethanol. Whole-genome sequencing of more than 30 evolved popul...
