Referring to following video, I would like to know on how slime mold solves the puzzle by forming the shortest path to foods source, if there are 2 possible paths to foods source, Slime mold should form 2 possible paths instead of a shortest path.
"The whole organism is made up of bits of pulsating tissue, which are constantly expanding and contracting." What is the key factor to make Slime mold expanding and contracting?
Does anyone have any suggestions on how chemical plays a role here?
Thanks in advance for any suggestions

Once the shortest path to foods source is found, what make Slime mold stop searching for another shorter path?
"Another experiment by Tanya Latty and Madeleine Beekman from the University of Sydney presented Physarum polycephalum with two food sources, one consisting of 1% oatmeal in darkness and one of 5% oatmeal in bright light, lethal to the slime mold. The slime mold crawled toward both equally, recognizing the trade-off between high food content and unfavorable conditions. However, when a third source containing 3% oatmeal in darkness was introduced, the slime mold showed preference to this food source. Eighty percent of the mold was found to grow toward the 3% solution. "

Thanks in advance for any suggestions
Case 1
1% oatmeal in darkness = 50%
5% oatmeal in bright light = 50%
Case 2
1% oatmeal in darkness = 10%
3% oatmeal in darkness = 80%
5% oatmeal in bright light = 10%
Does anyone have any suggestions on how to determine the formula for tradeoff between foods and light?
Thanks in advance for any suggestions
