Newman, William M. | An experimental display programming language for the PDP-10 computer | An experimental language for display programming, called DIAL, has been developed for the PDP-10 and the UNIVAC 1559 display. It is experimental in the sense that it was originally conceived as a means of testing out some ideas, and the best way to test them seemed to be to produce a language that ... | Display programming; DIAL; Display Algol | 1970 |

Myers, Chris J. | An improvement in partial order reduction using behavioral analysis | Efficacy of partial order reduction in reducing state space relies on adequate extraction of the independence relation among possible behaviors. However, traditional approaches by statically analyzing system model structures are often not able to reveal enough independence for reduction. To address ... | 2012-01-01 | |

Bruderlin, Beat | An interactive N-Dimensional constraint system | In this paper, we present a graph-based approach to geometric constraint solving. Geometric primitives (points, lines, circles, planes, etc.) possess intrinsic degrees of freedom in their embedding space. Constraints reduce the degrees of freedom of a set of objects.

Gopalakrishnan, Ganesh | An interface aware guided search method for error-trace justification in large protocols | Many complex concurrent protocols that cannot be formally verified due to state explosion can often be formally verified by initially creating a collection of abstractions (overapproximations), and subsequently refining the overapproximated protocol in response to spurious counterexample traces. ... | Concurrent protocols; Verification; Error-trace justification | 2008 |
