Several Google
searches in year 2011 on keyword ‘e-judgment’ or
‘electronic judgment’ have consistently ranked this document among the top
five. The other documents listed used the term in a different meaning (as
databases of judgments). So it appears that I am the
inventor of this term. We’ll see how useful it will be. In 1961, fresh from law
school, I was hired to study the uses that computers could have in legal
establishments. It then occurred to me that computers could help decide simple
legal cases. It took me fifty years to come up with a paper on this topic!

The concept of goal-oriented
execution for LOTOS was discovered almost simultaneously by our group and a
Dutch group (Ed Brinksma and Henk Eertink).
It is applicable to CCS and CSP, as well as to other process-algebraic
languages. However strangely, many years later, this extension has not been done, for what I know. It is a useful technique for state
exploration in infinite-state systems. The PhD thesis of Mazen Haj-Hussein,
that explained the concept in detail, is available in
the web.

Open
Distributed Processing (ODP) Tutorials
The Open Distributed Processing (ODP) concept was much
ahead of its time and is still of current interest.
Although this is not often recognized, the Service
Oriented Architecture (SOA) is based on ODP concepts.
Here are some tutorial papers and research reports
that we wrote quite a while ago (1993-1996), with my student Kazi Farooqui.
I think that they are still useful.

Very old papers
that haven’t been cited at all…
Some of my best papers are those that resulted from my
PhD thesis, years of work… with the help of my supervisors, John Brzozowski and
Ed Ashcroft, as well as the inspiration of my external examiner, Ray Miller.
They have received extremely few citations, probably because the topic has not
been fashionable. But I know that they are a lot better than some papers of
mine that have been cited dozens of times. So much for citation counts.
PDF Logrippo, L. Renamings and Economy of Memory in Program Schemata. J. ACM
25(1), (Jan. 1978), 10-22
It is possible to change the name of
the variables in programs in such a way that the results computed are
unchanged. This equivalence-preserving transformation is at the basis of
program optimizations such as efficient register allocation or efficient memory
allocation, used in optimizing compilers. This paper justifies theoretically
this transformation and explains how it works.
PDF Logrippo, L. Renamings,
Maximal Parallelism, and Space-Time Tradeoff in Program Schemata. J. ACM 26(4),
(Oct. 1979), 819 - 833
This paper continues the work
presented in the previous paper. It shows formally that by allocating more
memory space, more variables, or more registers, the parallelism of a program
can be increased. For example, the parallelism of a producer-consumer system
can be increased by increasing the length of the queue between the producer and
consumer. Pipelined processors with instruction look-ahead use the same
principle. This equivalence-preserving transformation can be applied
automatically in order to take advantage of
computational resources as they become available, at execution time or at
compilation time.
It is useful to
review the results of this paper in the light of Amdahl’s famous law. One of
several ways of interpreting this law states that the speedup that can be
obtained in the execution of a program P by using increasingly larger numbers
of processors in parallel computing arrangements is limited by the time needed
for executing the sequential parts of P. Amdahl’s law assumes that the
sequential and parallelizable parts of P are known in advance and cannot be
changed (unless the program is redesigned). This paper shows that: 1) it may be
possible to execute a program at different levels of parallelisms at different
points of execution 2) it may possible
to increase the parallelism of a program by spreading its working space in
memory, essentially by using queue or queue-like mechanisms. This paper also
characterizes the program structures where this can or cannot be done.
Intuitively, these concepts are well recognized in Computer Science
however here they are formally analyzed.
