historical understandings of architecture to include lesser or minor discourses that have influenced the development of architectural ideas over time. Studies in feminism in architecture, and in sexuality and gender as potent cultural expressions, are also considered an integral part of the latter 20th-century theoretical discourse, and are associated with such persons as Dolores Hayden, Catherine Ingraham, Jennifer Bloomer and Sylvia Lavin. The notion that theory entails critique also stemmed from post-structural literary studies in the work of many other theorists and architects, such as Mark Wigley and Diana Agrest, among others. In their theories, architecture is compared to a language which can be invented and re-invented every time it is used. This theory influenced the so-called deconstructivist architecture. In contrast, network society innovators, especially Silicon Valley software developers, have embraced Christopher Alexander's emphasis on The Timeless Way of Building (1979) based on pattern languages that are optimized on-site as construction unfolds. Since 2000, architectural theory has also had to face the rapid rise of urbanism and globalization. By developing a new understanding of the city, many theorists developed new understandings of the urban conditions of our planet (E.G. Rem Koolhaas's Bigness). Interests in fragmentation and architecture as transient objects further affected such thinking (e.g. the concern for employing high technology), but also related to general concerns such as ecology, mass media, and economism. In the past decade, there has been the emergence of the so-called "Digital" Architecture. Several currents and design methodologies are being developed simultaneously, some of which reinforce each other, whereas others work in opposition. One of these trends is Biomimicry, which is the process of examining nature, its models, systems, processes, and elements, to emulate or take inspiration from them in order to solve human problems. Architects also design organic-looking buildings in the attempt to develop a new formal language. Another trend is the exploration of those computational techniques that are influenced by algorithms relevant to biological processes and sometimes referred to as Digital morphogenesis. Trying to utilize Computational creativity in architecture, Genetic algorithms developed in computer science are used to evolve designs on a computer, and some of these are proposed and built as actual structures. Since these new architectural tendencies emerged, many theorists and architects have been working on these issues, developing theories and ideas such as Patrick Schumacher's Parametricism. Contemporary architecture's theoretical world is plural and multicolored. There are different dominant schools of
