I believe there is a small mix-up here:

Halide/src/autoschedulers/adams2019/FunctionDAG.cpp

Lines 269 to 275 in c0b5b11

for (size_t j = 0; j < stage.loop.size(); j++) {
bool single_one = (ones_per_col[j] == 1) && (zeros_per_col[j] == args.size() - 1);
bool all_zero = (zeros_per_col[j] == args.size());
is_transpose &= single_one || all_zero;
is_broadcast &= single_one;
is_slice &= single_one;
}

Halide/src/autoschedulers/anderson2021/FunctionDAG.cpp

Lines 267 to 273 in c0b5b11

for (size_t j = 0; j < stage.loop.size(); j++) {
bool single_one = (ones_per_col[j] == 1) && (zeros_per_col[j] == args.size() - 1);
bool all_zero = (zeros_per_col[j] == args.size());
is_transpose &= single_one || all_zero;
is_broadcast &= single_one;
is_slice &= single_one;
}

The is_transpose flag should satisfy: single one per row AND single one per column.
And for is_broadcast it should be: single one per row AND (single one OR all zeros) per column.
