Among various traditional art forms, brush stroke drawing is one of the widely used styles in modern computer graphic tools such as GIMP, Photoshop and Painter. In this paper, we develop an AI-aided art authoring (A4) system of nonphotorealistic rendering that allows users to automatically generate brush stroke paintings in a specific artist’s style. Within the reinforcement learning framework ...

Given a graph H and an integer r ≥ 2, let G → (H, r) denote the Ramsey property of a graph G, that is, every r-coloring of the edges of G results in a monochromatic copy of H. Further, let m(G) = maxF⊆G |E(F )|/|V (F )| and define the Ramsey density minf (H, r) as the infimum of m(G) over all graphs G such that G → (H, r). In the first part of this paper we show that when H is a complete graph ...

Tim nineteenth-century artist Richard Dadd, who spent most of his working life confined in the Criminal Lunatic Asylums at Bethlem and Broadmoor, is quite well known, and ever increasingly so, to the art world; his name is less well known, perhaps, in the sphere of psychiatric history. Dadd was born at Chatham in 1817, the third son and fourth child of Robert Dadd, who owned a chemist's busines...
