Flowstar
2024
​​
v0.2.1 - Flowstar now calculates linear (2-Norm/Euclidean) distances alongside constructing the quasimetric embedding. This change was made for support for EPAQS v0.3.0.
​
v0.2.0 - Flowstar now handles 8-directional search. This makes Flowstar better able to assess distances in mines that are not room-and-pillar.

v0.1.0 - Alpha Release
EPAQS
2024
​​
v0.3.1 - Performance improvements. EPAQS now runs 1-2 orders of magnitude faster than previous versions and can handle much, much larger mine layouts.
​
v0.3.0 - EPAQS now auto-generates sensor configuration files alongside the results output. There are two file types: .ldm for the linear distance matrix and .qem for the quasimetric embedding matrix. These two file types will support SAM-UG and dramatically reduce computational overhead in SAM-UG v0.1.0. Sensor IDs are automatically assigned from 000-999 in increasing numbers but reach out if you need a more custom solution. Sensor IDs must remain consistent between EPAQS .ldm and .qem files and the real-time data feed for the SAM-UG software. The addition of this feature makes EPAQS take a while longer to run. I am working to improve the file read speed and will have a far faster version available in v0.4.0.
​​
v0.2.0 - EPAQS now accepts an optional, separate "boundary" file. This constrains sensor placements to user-specified locations. (This constraint also makes the program run much, much faster!) Users can now choose to only place sensors on ribs or in critical locations. EPAQS will still provide an optimized partition, but a true "optimal" partition will still require sensors to be placed on the back of the excavation.
