UPMP

Parallel IDA* solver written in C++ with pybind11.

Installation

pip install -e .

Usage

from UPMP import idaStar

lanes = [
    [1, 2, 3],
    [1, 2, 3],
]

result = idaStar(
    lanes,
    log_fn=None,
    stop_get_best_fn=None,
    stop_fn=None,
    use_dsg_tiebreak=False,
    num_threads=8,
)

print(result)

The native module is still available as ida_star_cpp for existing code.

Stack area generation

from UPMP import stackAreaGenerator

depo = stackAreaGenerator(
    width=9,
    length=9,
    height=2,
    fill_pct=60,
    access="NSWE",
    max_priority=5,
    seed=123,
)

print(depo["priorities"])

Access direction fixing

from UPMP import accessDirectionFixing, idaStar

lanes, lane_matrix = accessDirectionFixing(depo)

details, lane_matrix = accessDirectionFixing(depo, return_details=True)
print(details["lanes"])

# lane_matrix is padded to width * length * height slots.
result = idaStar(lane_matrix)
