Ising machines can find optimum or quasi-optimum solutions of combinatorial optimization problems efficiently and effectively. The graph coloring problem, which is one the difficult problems, to assign a color each vertex such that no two vertices connected by an edge have same color. Although methods map problem onto model quadratic unconstrained binary (QUBO) are proposed, none them considers...

This paper proposes a stable modifiable walking pattern generator with a vertical foot motion generated by a central pattern generator that is obtained from the evolutionary constrained optimization. A modifiable walking pattern generator is employed which generates sagittal and lateral position trajectories of center of mass of humanoid robot and a CPG generates the vertical foot trajectory of...

To ensure stability of learning, state-of-the-art generalized policy iteration algorithms augment the policy improvement step with a trust region constraint bounding the information loss. The size of the trust region is commonly determined by the Kullback-Leibler (KL) divergence, which not only captures the notion of distance well but also yields closed-form solutions. In this paper, we conside...

We study consumer liquidity in a general equilibrium model where the friction is the nonpledgeability of future income. Liquidity helps to overcome the absence of a double coincidence of wants. Consumers over-hoard liquidity and the resulting competitive equilibrium is constrained inefficient. Fiscal policy following a large negative shock can increase ex ante welfare. If the government cannot ...

objective(s) several antigens, adjuvants and delivery systems have been evaluated for induction of protective immune responses against leishmaniasis, but most of them have been inefficient. in this study, plga nanospheres as antigen delivery system cpg-odn as an immunoadjuvant for increasing the immune responses against autoclaved leishmania major (alm) were prepared and characterized. material...

Concerns regarding the Trans-Pacific Partnership (TPP) have raised awareness about the negative public health impacts of trade and investment agreements. In the past decade, we have learned much about the implications of trade agreements for public health: reduced equity in access to health services; increased flows of unhealthy commodities; limits on access to medicines; and constrained policy...

The degree-constrained subgraphs decomposition problem, such as an f-coloring, an f-factorization, and a [ g, f ]-factorization, is to decompose a given graph G=(V, E) to edge-disjoint subgraphs degree-constrained by integer-valued functions f and g on V. In this paper we show that the problem can be simply reduced to the edge-coloring problem in polynomial-time. That is, for any positive integ...

The demand of two-dimensional source coding and constrained coding has been getting higher these days, but compared to the one-dimensional case, many problems have remained open as the analysis is cumbersome. A main reason for that would be because there are no graph representations discovered so far. In this paper, we focus on a two-dimensional finite type constrained system, a set of two-dime...
