The complexity of algorithms that compute strategies or operate on them typically depends on the representation length of the strategies involved One measure for the size of a mixed strategy is the number of strategies in its support the set of pure strategies to which it gives positive probability This paper investigates the existence of small mixed strategies in exten sive form games and how ...

Dercum's disease is a rare disorder with subcutaneous formation of fatty tissue (lipomas) with symptoms of pain, fatigue, stiffness, weakness and in some cases arthritis. The rarity of this disease causes that it is not taken into consideration in the rheumatological differential diagnosis, so this short report draws attention to this rare disease.

Dynamical systems, such as electric circuits, mechanical systems, and chemical plants, can be modeled by mixed matrix pencils, i.e., matrix pencils having two kinds of nonzero coefficients: fixed constants that account for conservation laws and independent parameters that represent physical characteristics. Based on dimension analysis of dynamical systems, Murota (1985) introduced a physically ...

This paper presents an improved algorithm for computing the Combinatorial Canonical Form (CCF) of a layered mixed matrix A = Q T , which consists of a numerical matrix Q and a generic matrix T . The CCF is the (combinatorially unique) nest block-triangular form obtained by the row operations on the Q-part, followed by permutations of rows and columns of the whole matrix. The main ingredient of ...

Biological samples of free-ranging dolphins are increasingly used to gain information on population structure and ecology. In small cetaceans, the gender of individuals usually cannot be determined at sea, and population sex ratio has to be inferred indirectly. We used molecular sexing to determine the gender of 340 biopsy samples of bottlenose dolphins, Tursiops truncatus, spotted dolphins, St...

The complexity of algorithms that compute strategies or operate on them typically depends on the representation length of the strategies involved. One measure for the size of a mixed strategy is the number of strategies in its support the set of pure strategies to which it gives positive probability. This paper investigates the existence of "small" mixed strategies in extensive form games, and ...

In this paper we present a convergence analysis for the space discretization of hyperbolic evolution problems in mixed form. The results of [1] are extended to this situation, showing the relationships between the approximation of the underlying eigenvalue problem and the space discretization of the corresponding evolution problem. The theory is applied to the finite element approximations of t...
