What is 'Open'? An Economic Analysis of Open Institutions

Feng Frederic Deng
2008 Social Science Research Network  
By examining several different types of open institutions including open source software, open science, open square and (open) urban planning, this paper presents a general analysis of open institutional  ...  In addition to providing a general definition of open institutional structure, we submit there are two necessary conditions for open institutions.  ...  In order to have a general understanding of the reasons for open institutions, the first question then becomes crucial since open institutional structure may only be efficient when producing some particular  ...

Real-world robotics: Learning to plan for robust execution

Scott W. Bennett, Gerald F. Dejong
1996 Machine Learning  
In executing classical plans in the real world, small discrepancies between a planner's internal representations and the real world are unavoidable.  ...  Permissive planning, a machine learning extension to classical planning, is one response to this difficulty.  ...  For permissive planning to help, internal representations must be reasonable approximations to the world.  ...
