    High-quality and timely marine environmental information will nourish mitigation and protection strategies in the face of significant challenges and threats, such as natural disasters, habitat loss, human and species migration, and food security, together with the deprivation due to marine-related industry activities, tourism, and recreation. EMSO ERIC will provide bio-geophysical, and chemical information needed to monitor the impact of climate change on the ocean system, mitigation of geo-hazards risk, and progress in deep-sea habitat mapping. EMSO ERIC will promote the creation of new hi-tech jobs, and spur the development of innovative applications and services in strategic industrial sectors such as marine robotics, blue biotech, offshore aquaculture, seabed resources, smart submarine cables, marine renewable energy, pharmaceutical, fishing and tourism

    Zero Knowledge and Circuit Minimization

    No full text
    We show that every problem in the complexity class SZK (Statistical Zero Knowledge) is efficiently reducible to the Minimum Circuit Size Problem (MCSP). In particular Graph Isomorphism lies in RP MCSP. This is the first theorem relating the computational power of Graph Isomorphism and MCSP, despite the long history these problems share, as candidate NP-intermediate problems.Peer reviewe

    Syntactic separation of subset satisfiability problems

    Variants of the Exponential Time Hypothesis (ETH) have been used to derive lower bounds on the time complexity for certain problems, so that the hardness results match long-standing algorithmic results. In this paper, we consider a syntactically defined class of problems, and give conditions for when problems in this class require strongly exponential time to approximate to within a factor of (1 − ε) for some constant ε > 0, assuming the Gap Exponential Time Hypothesis (Gap-ETH), versus when they admit a PTAS. Our class includes a rich set of problems from additive combinatorics, computational geometry, and graph theory. Our hardness results also match the best known algorithmic results for these problems.Peer reviewe

    Better Complexity Bounds for Cost Register Automata

    No full text
    Cost register automata (CRAs) are one-way finite automata whose transitions have the side-effect that a register is set to the result of applying a state-dependent semiring operation to a pair of registers. Here it is shown that CRAs over the tropical semiring can simulate polynomial time computation, proving along the way that a naturally dened width-k circuit value problem over the tropical semiring is P-complete. Then the copyless variant of the CRA, requiring that semiring operations be applied to distinct registers, is shown no more powerful than NC^1 when the semiring is the integers, or strings with operations max and concat. This relates questions left open in recent work on the complexity of CRA-computable functions to long-standing class separation conjectures in complexity theory, such as NC versus P and NC^1 versus GapNC^1.Peer reviewe
