Re: [code jam] Qualifications 2022 Twisty Little Passages Analysis Importance Sampling

I see your point. The difference between our computations is how we interpret the phrase "weighted average". My interpretation was the following: if we have values {v_i} with weights {w_i} then the weighted average WA = (sum_{i=1..N} v_i * w_i) / (sum_{i=1..N} w_i). The important part is that th

@Ricola, The formula for weighted average is Sum(value * weight) / Sum(weight) In your case, you have 500 room, with one passage, with weight 1 and you have 500 rooms with 9 passages and with weight 500/9 So Sum(value * weight) = 500 * 1 + 9 * 500 / 9 = 1000 and Sum(weight) = 50
