A Universal Modular ACTOR Formalism for A r t i f i c i a l Intelligence Carl Hewitt Peter Bishop Richard Steiger Abstract This paper proposes a modular ACTOR architecture and definit ional method for a r t i f i c i a l intelligence that is conceptually based on a single kind of object: actors [or, if you w i l l , v i r tual processors, activation frames,(More)

This paper presents some laws that must be satisfied by computations involving communicating parallel processes. The laws are stated in the context of the actor theory, a model for distributed parallel computation, and take the form of stating plausible restrictions on the histories of parallel computations to make them physically realizable. The laws are(More)
Biogenic volatile organic compounds produced by plants are involved in plant growth, development, reproduction and defence. They also function as communication media within plant communities, between plants and between plants and insects. Because of the high chemical reactivity of many of these compounds, coupled with their large mass emission rates from(More)
<bold>This paper investigates some problems associated with an argument evaluation order that we call &#8220;future&#8221; order, which is different from both call-by-name and call-by-value, In call-by-future, each formal parameter of a function is bound to a separate process (called a &#8220;future&#8221;) dedicated to the evaluation of the corresponding(More)
This paper is intended as a contribution to analysis of the implications of viewing offices as open systems. It takes a prescriptive stance on how to establish the information-processing foundations for taking action and making decisions in office work from an open systems perspective. We propose <italic>due process</italic> as a central activity in(More)
