We illustrate the importance of branching in planning by exploring alternative branching schemes in Graphplan. As argued elsewhere, Graphplan can be understood as a heuristic search planner that performs an IDA* regression search with a heuristic function encoded in the plan graph. Here, we study two alternatives to Graphplan where the IDA* search algorithm and the heuristic encoded in the plan...

Aims: Evolutionary branching is a process of evolutionary diversification induced by frequency-dependent ecological interaction. Here we show how to predict the occurrence of evolutionary branching in bivariate traits when populations are evolving directionally. Methods: Following adaptive dynamics theory, we assume low mutation rates and small mutational step sizes. On this basis, we generaliz...

We consider a continuous-time symmetric branching random walk on multidimensional lattice with finite set of particle generation centers, i.e., sources. The existence positive eigenvalue the evolutionary operator means exponential growth first moment total number particles both at an arbitrary point and entire lattice. Branching walks or negative intensities sources that have simplex configurat...

In many experiments, some of the factors exist only within the level of another factor. Such factors are often called nested factors. A factor within which other factors are nested is called a branching factor. For example, suppose we want to experiment with two processing methods. The factors involved in these two methods can be different. Thus, in this experiment the processing method is a br...

Abstract Panicle branching is one of the characters that can distinguish rice cultivar from another. Agricultural practices determined performance panicle branching. The trial aimed to study differences among ten lines based on cultivated good farming practices. Seven pure and three varieties were planted as genetic material in 4 replications. was conducted Bandung 2020 at an altitude 460 m asl...

Peripheral nerve injury-induced structural and chemical modifications of the sensory circuits in the dorsal horn of the spinal cord contribute to the mechanism of neuropathic pain. In contrast to the topographic projection of primary afferents in laminae I-IV in the rat spinal cord, the primary afferents of Macaca mulatta monkeys almost exclusively project into laminae I-II of the spinal cord. ...

These experiments investigate the photodissociation of methyl vinyl ether at 193 nm in a crossed laser-molecular beam apparatus. We observe two C–O bond fission channels, a minor channel producing CH31CH2CHO (X̃ A9) and the major channel yielding CH31CH2CHO (à A8). Some of the neutral à state vinoxy product undergoes secondary dissociation to produce ketene1H. These experiments on the photodisso...
