If what you need is to run or reference tiny_gp in .Net or mono, you can
also use IKVM.NET <[link]>. I'm using it to run ECJ in .Net
and works fine.

Cisco Tries to Break Out of the Data Center Role

2008-09-25T18:46:23Z

SAN JOSE, Calif. — Forget the switches and routers that built Cisco
Systems into a giant, albeit somewhat boring, company at the core of
the Internet.

These days, the company is peddling e-mail software, video
conferencing systems, cable TV boxes — even furniture — as it tries to
break out of the data center and get its products in front of ordinary

However, there exists several benchmarks that can be used to validate
evolutionary computation, but most of them are problem-centered.
Hopefully, the CEC benchmarks is specifically designed to compare
evolutionary algorithms, thus being a nice tool to start
experimentations :

We don't have test data of the type you mention. Because of the use of
random number generators, it is difficult to compare results across
implementations in different languages. So, unless you had exactly the
same random number generator implementation, there would be
differences in the output produced (even if we gave both generators

I am attempting to convert the tiny_gp.java to c#.

Are there any test cases available (i.e. fitness data with a know
result set)?

Thanks!

A question about your TinyGP

2008-08-17T19:36:49Z

I downloaded Genetic Programming program (tiny_gp.java) from the web
page of professor Riccardo Poli and run it with and sin-data.txt file
(also downloaded from tiny gp web page) but each time I run the
program I get the message 'Problem *Not* solved', I increased the
number of generations from 100 to 10000 but at generation 280 I get an

Hi,

the run procedure implements a recursive interpreter. It treats every
primitive as a macro, so the primitive must itself invoke the
interpreter (run) if and when necessary. So, it is essentially the
same algorithm as the one you refer to. However, for efficiency
reasons, we keep the code that implements each primitive within the

hi,

algorithm 3.1 (page 25) tells about Interpreter for GP, is this
algorithm have any relation with the evaluation procedure (run)?
because it is written (by a comment) that this method is interpreter.
is this algorithm will hep me to make changes the evaluation procedure
(run)?

thank you for helping me learn more clearly,

Hi Lyani,

Tiny GP can use variables and random constants. The first line of the
input data file tells the program how many variables your problem has,
then it tells it how many random constants GP can use, and then it
provides two values that represent the range (min,max) from which the
random constants are drawn. (The final element if the first line is

People in our group wanted to see more info about the population size
and number of gens and computer time to solve different kinds of
problems. I suppose it's a thankless task, but something as simple as
a giant table would be great. Maybe someone could put up a empty table
on a wiki page and invite folks in the GP community to fill in the

some question

2008-05-14T06:11:37Z

hello,

it's written on section B.1 about characteristics of TinyGP, and point
1 said that the terminal is a user-definable number of floating point
variables (named x1 to xn).

is it mean that TinyGP only use variables (one of the terminal set
mentioned on table 3.1) as the terminal?
is it mean TinyGP can't use constant values and 0-arity functions

I think it would help if we knew more about the nature of your project
and what you're trying to accomplish. There have been a number of
papers on combining GP and PSOs (Riccardo and Bill being authors of
several), so it certainly can be done. Riccardo's TinyGP code is
fairly specialized for symbolic regression problems, however, and

hi again,

i'm studying GP, and i'm trying to extend PSO using GP. Then i
realized that the paper that i refer to was written by you, entitled
"extending PSO via GP" (correct me if i'm wrong).

is it possible to use tiny GP as the GP program on this paper?
if it's not, is the book "field guide to GP" quite help to develop a

We have produced an HTML version of the book. It is not perfect but we
think it may be usable (and, hopefully, useful). This is available at

Cheers.
