Algorithm
The word "algorithm" itself derives from the 9th century mathematician Muḥammad ibn Mūsā al-Khwārizmī, Latinized "Algoritmi". A partial formalization of what would become the modern concept of algorithm began with attempts to solve the Entscheidungsproblem (decision problem) posed by David Hilbert in 1928. Later formalizations were framed as attempts to define "effective calculability" or "effective method". Those formalizations included the Gödel–Herbrand–Kleene recursive functions of 1930, 1934 and 1935, Alonzo Church's lambda calculus of 1936, Emil Post's Formulation 1 of 1936, and Alan Turing's Turing machines of 1936–37 and 1939.
Roman Verostko
Roman Verostko (born September 12, 1929) is an American artist and educator who creates code-generated imagery, known as algorithmic art. Verostko developed his own software for generating original art based on form ideas he had developed as an artist in the 1960s. His software controls the drawing arm of a machine known as a pen plotter that was designed primarily for engineering and architectural drawing. In coding his software Verostko conceives of the machine's drawing arm as an extension or prosthesis for his own drawing arm. The plotter normally draws with ink pens but Verostko adapted oriental brushes to fit the drawing arm and wrote interactive routines for achieving brush strokes with his plotters. In 1995, he co-founded the Algorists with Jean-Pierre Hébert.
