1. Reinforcement learning for graph theory, II. Small Ramsey numbersMohammad Ghebleh, Salem Al-Yakoob, Ali Kanso, Dragan Stevanović, 2025, original scientific article Abstract: We describe here how the recent Wagner’s approach for applying reinforcement learning to construct examples in graph theory can be used in the search for critical graphs for small Ramsey numbers. We illustrate this application by providing lower bounds for the small Ramsey numbers R(K_{2, 5}, K_{3, 5}), R(B₃, B₆) and R(B₄, B₅) and by improving the lower known bound for R(W₅, W₇).
Keywords: Ramsey number, critical graph, reinforcement learning, cross-entropy method

4. Sizes of eight oviparous elasmobranch species hatched in two Mediterranean areas : a survey and recent dataChristian Capapé, Mohamed Ben Salem, Mohamed Mourad Ben Amor, 2007, original scientific article Abstract: In the present paper, the authors report on the size of eight oviparous elasmobranch species hatched in two Mediterranean areas: off the Tunisian coast (central Mediterranean) and Languedocian coast (southern France, northern Mediterranean). Most of the observations were made in experimental conditions, from egg cases placed in tanks. For each species, no intraspecific variation was observed between specimens from both areas. In contrast, new hatched small spotted catsharks from the Mediterranean appeared to be smaller than those from the Atlantic.
