# Last-Passage Percolation with constraints, and applications to polymers in random environment

Hammersley’s Last-Passage Percolation (LPP) problem can be described as follows: let m points be drawn uniformly and independently in [0,1]^2, then what is the maximal number of points that can be collected by an up-right path? In this talk, I will introduce a generalization of this problem, where the up-right condition is changed to a global condition on the path. Results on this new LPP with constraints are limited, but they already have some applications, in particular in the context of polymers in random environment.
