This paper deals with different models of random walks with a reinforced memory of preferential attachment type. We consider extensions of the Elephant Random Walk introduced by Schütz and Trimper [2004] with a stronger reinforcement mechanism, where, roughly speaking, a step from the past is remembered proportional to some weight and then repeated with probability $p$. With probability $1-p$, the random walk performs a step independent of the past. The weight of the remembered step is increased by an additive factor $b\geq 0$, making it likelier to repeat the step again in the future. A combination of techniques from the theory of urns, branching processes and $α$-stable processes enables us to discuss the limit behavior of reinforced versions of both the Elephant Random Walk and its $α$-stable counterpart, the so-called Shark Random Swim introduced by Businger [2018]. We establish phase transitions, separating subcritical from supercritical regimes.
