The Planning Domain Definition Language (PDDL) is an attempt to standardize Artificial Intelligence (AI) planning languages. It was first developed by Drew McDermott and his colleagues in 1998 (inspired by STRIPS and ADL among others) mainly to make the 1998/2000 International Planning Competition (IPC) possible, and then evolved with each competition. "The adoption of a common formalism for describing planning domains fosters far greater reuse of research and allows more direct comparison of systems and approaches, and therefore supports faster progress in the field. A common formalism is a compromise between expressive power (in which development is strongly driven by potential applications) and the progress of basic research (which encourages development from well-understood foundations). The role of a common formalism as a communication medium for exchange demands that it is provided with a clear semantics."
Famous quotes containing the words planning, domain, definition and/or language:
“My consciousness-raising group is still going on. Every Monday night it meets, somewhere in Greenwich Village, and it drinks a lot of red wine and eats a lot of cheese. A friend of mine who is in it tells me that at the last meeting, each of the women took her turn to explain, in considerable detail, what she was planning to stuff her Thanksgiving turkey with. I no longer go to the group.”
—Nora Ephron (b. 1941)
“Without metaphor the handling of general concepts such as culture and civilization becomes impossible, and that of disease and disorder is the obvious one for the case in point. Is not crisis itself a concept we owe to Hippocrates? In the social and cultural domain no metaphor is more apt than the pathological one.”
—Johan Huizinga (1872–1945)
“The man who knows governments most completely is he who troubles himself least about a definition which shall give their essence. Enjoying an intimate acquaintance with all their particularities in turn, he would naturally regard an abstract conception in which these were unified as a thing more misleading than enlightening.”
—William James (1842–1910)
“So runs my dream: but what am I?
An infant crying in the night;
An infant crying for the light:
And with no language but a cry.”
—Alfred Tennyson (1809–1892)
