For KRS we set the probabilities to0.5, the number of stepsbetween records to±=4, and the total number of steps to105. Because±was sosmall, the samples were highly correlated, but the estimates are still quite good.C(0)C(1)C(2)C(3)C(4)C(5)C(6)C(7)C(8)2×21422×3171133×31124456184×41242241044259333882150552366×616016222617228151421353561178538248145820146702793(b) One of the more interesting programming issues in this problem is thedatastructure.•If we keep track of eachedgeof the lattice, then we need to enumerate rulesfor deciding whether two edges can be covered at the same time.
