- Abstract: Multi Expression Programming (MEP) is a Genetic Programming variant which
encodes multiple solutions in a single chromosome. This paper introduces and
deeply describes several strategies for solving binary and multi-class
classification problems within the \textit{multi solutions per chromosome}
paradigm of MEP. Extensive experiments on various classification problems are
performed. MEP shows similar or better performances than other methods used for
comparison (namely Artificial Neural Networks and Linear Genetic Programming).

A new Genetic Programming variant called Liquid State Genetic Programming (LSGP) is proposed in this paper.
LSGP is a hybrid method combining a dynamic memory for storing the inputs (the liquid) and a Genetic Programming technique used for the problem solving part.
Numerical experiments show that LSGP performs similarly and sometimes even better than standard Genetic Programming for the considered test problems.

As a byproduct of our analysis we introduce a novel regularization process over vanilla descent and provide theoretical and experimental evidence that it helps address vanishing-gradient issues and escape bad stationary points.

Cutting plane type methods can handle multistage problems with a large number of stages, but a relatively smaller number of state (decision) variables.

We investigate the possibility of encoding multiple solutions of a problem in a single chromosome.
In order to obtain some benefits the chromosome decoding process must have the same complexity as in the case of a single solution in a chromosome.
