Abstract: Implementations generally relate to generating circuits. In one implementation, a method includes generating accumulated statistics, where the generating of the accumulated statistics is repeated based on one or more generation criteria. In some implementations, the generating of the accumulated statistics includes generating one or more changed versions of a current circuit, where the current circuit includes logic cells that perform Boolean operations, generating statistics associated with performance of the one or more changed versions based on the application of a training set to each changed version, and adding the generated statistics associated with each changed version to the accumulated statistics. The method further includes selecting a changed version from the one or more changed versions based on the accumulated statistics, updating the current circuit based on the selected changed version, and repeating the method multiple times based on the accumulated statistics.

Abstract: The invention is a single piece of ultralight backpacking gear that can be configured to a cloak, a one person bivy tent and can be joined to a cloak of the same design to form a two person tent.

Abstract: A backpack containing a gravity flow water filtration system. The backpack incorporates a compartment at its top to hold a reservoir of untreated water, and a compartment at the bottom to hold a reservoir for filtered water. A tube and filter connect the two compartments, and a drinking tube and mouthpiece allow the user of the backpack to drink filtered water from the filtered water reservoir. In some embodiments, the bottom compartment is accessible from both ends, and can store other items as well.

Abstract: An ultra-light stove and cook pot that when packed up for storage convert to an insulated cup, comprising a cook pot, a windscreen, a stand and a tray for suspending a burning fuel tablet. Packed up for storage, the cook pot functions as a cup, the tray insulates the bottom of the cup, the windscreen insulates the sides of the cup, and the stand encircles and holds everything securely in place.
