This paper presents a navigation component based on a hybrid case-based reasoning (CBR) and reinforcement learning (RL) approach for an AI agent in a real-time strategy (RTS) game. Spatial environment information is abstracted into a number of influence maps. These influence maps are then combined into cases that are managed by the CBR component. RL is used to update the case solutions which ar...

We study the cohomology arising in the BRST formulation of G/H gauged WZNW models, i.e. in which the states of the gauged theory are projected out from the ungauged one by means of a BRST condition. We will derive for a general simple group H with arbitrary level, conditions for which the cohomology is non-trivial. We show, by introducing a small perturbation due to Jantzen, in the highest weig...

The consumption of high-quality pollen induces the development of the hypopharyngeal glands in young honey bee workers. As protein-rich secretions from these glands are an important component of larval food, a direct relationship between pollen supply and brood rearing can be suspected. Consequently, the availability of pollen is likely to be a central parameter influencing the development of h...

We develop the algebraic polynomial theory for " supertropical algebra, " as initiated earlier over the real numbers by the first author. The main innovation there was the introduction of ghost elements, which play the key role in our structure theory. Here, we work in a slightly more general situation over an arbitrary semiring, and develop a theory which contains the analogs of the basic theo...

The two-component formulation of quantum electrodynamics is studied. The relation with the usual Dirac formulation is exhibited, and the Feynman rules for the two-component form of the theory are presented in terms of familiar objects. The transformation from the Dirac theory to the two-component theory is quite amusing, involving Faddeev-Popov ghost loops of a fermion type with bose statistics...

We construct a local, gauge-fixed, lattice Yang-Mills theory with an exact BRST invariance, and with the same perturbative expansion as the standard Yang-Mills theory. The ghost sector, and some of its BRST transformation rules, are modified to get around Neuberger’s theorem. A special term is introduced in the action to regularize the Gribov horizons, and the limit where the regulator is remov...

One hundred eighty-one Boer-sired goat kids from dams of predominantly Spanish breeding (17.6 ± 2.34 kg initial BW; 177 wethers, 4 doelings) were used to determine optimum inclusion level of concentrate in diets fed to goats in confinement. Effects of elevated loafing areas on performance were also examined. Goats were blocked by weight (2 blocks per treatment) and randomly assigned to 1 of 12 ...

In the B method, the invariant of a component cannot be violated outside its own operations. This approach has a great advantage: the users of a component can assume its invariant without having to prove it. But, B users must deal with important architecture restrictions that ensure the soundness of reasonings involving invariants. Moreover, understanding how these restrictions ensure soundness...

The present study was initiated to determine whether walking ability (WA) could be markedly improved without seriously compromising growth rate and body conformation by crossing a relatively unimproved commercial sire line (UC) with a line (FL) selected for increased shank width and backcrossing F1 females to UC line males. Body weights at 8, 16, and 20 wk of age were generally similar for both...

We find new special physical operators of W3−gravity having non trivial ghost sectors. Some of these operators may be viewed as the liouville dressings of the energy operator of the Ising model coupled to 2d gravity and this fills in a gap in the connection between pure W3−gravity and Ising model coupled to 2d gravity found in our previous work. We formulate a selection rule required for the ca...
