A classical result of Komlós, Sárközy, and Szemerédi states that everyn‐vertex graph with minimum degree at least (1/2 +o(1))ncontains everyn‐vertex tree with maximum degree . Krivelevich, Kwan, and Sudakov proved that for everyn‐vertex graphGαwith minimum degree at leastαnfor any fixedα> 0 and everyn‐vertex treeTwith bounded maximum degree, one can still find a copy ofTinGαwith high probability after addingO(n) randomly chosen edges toGα. We extend the latter results to trees with (essentially) unbounded maximum degree; for a given andα> 0, we determine up to a constant factor the number of random edges that we need to add to an arbitraryn‐vertex graph with minimum degreeαnin order to guarantee with high probability a copy of any fixedn‐vertex tree with maximum degree at most Δ.
