The decomposition theorems that are\nknown for even-hol e-free graphs are seemingly more powerful than the\nones for perfect graph s: the basic classes and the decompositions are\nin some respect more res tricted. But strangely\, in an algorithmic\nperpective\, much more is know n for perfect graphs. \n DTSTAMP:20250521T223108Z END:VEVENT END:VCALENDAR
