Webb1 sep. 2024 · In this paper, we consider the values of R (T_n,K_s+C_6) and R (T_n,K_s+C_7). Our main results are the followings. Theorem 4 R (T_n,K_s+ C_6)= (s+1) (n-1)+1 for s\ge 2 and n\ge 5. Additionally, we obtain the Ramsey number R (T_n,K_s+C_7) easily. Theorem 5 R (T_n,K_s+ C_7)= (s+2) (n-1)+1 for s\ge 1 and n\ge 5.

WebbAt present, research on Ramsey Numbers has expanded to a wider scope, not only between 2 complete graphs that are complementary to each other but also a combination of complete graphs, circle graphs, star graphs, wheel graphs, and others. While the WebbOur starting set of graphs consisted of R(6), which contains 5017 nonisomorphic graphs as found in [12]. By extending appropriate subfamilies of R(6), we first 3 obtained R(7,n) for all n≥ 16. Table II includes some data about these constructed graphs, confirming and extending the previous results about R(7) presented in [12]. round robin scheduling in rtos

Webb19 mars 2024 · Georgia Tech & Morningside College Actually determining the Ramsey numbers R ( m, n) referenced in Theorem 11.2 seems to be a notoriously difficult problem, and only a handful of these values are known precisely. In particular, R ( 3, 3) = 6 and R ( 4, 4) = 18, while 43 ≤ R ( 5, 5) ≤ 49.
