Pittrap

tamuctf

Task: ONNX neural network model that scores 48-char inputs, find the flag that maximizes score. Solution: All optimization methods (gradient descent, Gumbel-Softmax, SA, GA) converge to same local optimum with garbled middle. The flag is a thematic phrase 'catch the local max' that scores higher than the trap.
