The previously known best approximation ratio for MaxIM on C5-free d-regular graphs is $\left(\frac{3d}{4}-\frac{1}{8}+\frac{3}{16d-8}\right)$. In this paper, we design a $\left(\frac{2d}{3}+\frac{1}{3}\right)$-approximation algorithm, whose approximation ratio is strictly smaller/better than the previous one when d≥6.}, pages = {1142--1149}, title = {An Approximation Algorithm for the Maximum Induced Matching Problem on C5-Free Regular Graphs}, volume = {E102-A}, year = {2019}, yomi = {ミヤノ, エイジ} }
