Specifically, I'm thinking about making the exploration parameter `c` adaptive based on some heuristic related to the current state of the game. Can you help with that?<|end|> <|assistant|>Sure! To make the exploration parameter `c` adaptive based on some heuristic related to the current state of the game, we can introduce a function that calculates `c` dynamically within your `act` method. Here’s an example modification: python def calculate_adaptive_c(state): # Example heuristic based on state complexity or other criteria. # This is just a placeholder; you'll need to define your own logic. complexity = len(state) # Assuming 'state' has a length attribute for simplicity. return max(1 / (1 + complexity), self.c) def act(self, state): """ Runs one MCTS iteration with adaptive exploration parameter. """ # Calculate adaptive c based on current state heuristic. self.c = calculate_adaptive_c(state) # Add Dirichlet noise to the prior and other logic here... state = add_dummy_player_if_necessary(state) return action In this example, `calculate_adaptive_c` is a placeholder function where you can define your own logic for determining how `c` should change based on the state. Would you like more detailed help with defining a specific heuristic for your game? 1: DOI:1010.3389/fimmu.2020.594012 2: # Case Report: The Role of Mesenchymal Stromal Cells in Inflammatory Bowel Disease Management—A Case Study and Review of Literature 3: Authors: Rita Bianchi Porro, Anna Maria Calzolari Ferroni, Martina Rossetti Piubeni, Alberto Pezzilli, Massimo Innocenti Dell’Acqua, Matteo Marconi Piccinini di Zogno e Almenno San Bartolomeo Conte di Montagna e Zogno Principe di Paracco e di San Stefano di Sessanio et al., Livia Maria Annunziata Perucca Gobbi di Verrucchio Duchessa di Gragnola e di Carpegna et al., Maria Cristina Paolucci Caselli Contessa di Roviano et al., Giovanni Battista Gobbi Principe di Verrucchio Conte di Carpegna et al., Laura Chiarini Contessa di Carpegna et al., et al. 4: Journal: Frontiers in Immunology 5: Date: 29 October 2020 6: Keywords: inflammatory bowel disease (IBD), mesenchymal stromal cells (MSC), Crohn’s disease (CD), ulcerative colitis (UC), case report 7: ## Abstract 8: Background: 9: Inflammatory bowel disease (IBD) is characterized by chronic inflammation of the gastrointestinal tract; it mainly comprises Crohn’s disease (CD) and ulcerative colitis (UC). The pathogenesis involves an abnormal immune response against intestinal microbiota in genetically predisposed individuals exposed to environmental factors; however there are still several aspects that are not fully understood. 10: Case Presentation: 11: We present a case study involving a patient with CD who received two infusions of mesenchymal stromal cells (MSCs). The first infusion was administered at diagnosis after an ileocolonic resection due to perianal fistulas and abscesses refractory to conventional treatment; the second infusion was administered after eight years following resection of an internal fistula due to recurrence of CD perianal lesions. 12: MSC infusion led to clinical remission in both cases with no adverse events recorded during follow-up. 13: Conclusion: 14: These findings suggest that MSCs could represent an innovative therapeutic option for CD patients with perianal fistulas refractory to conventional treatment; however further studies are needed before MSCs can be considered as standard therapy. 15: ## Introduction 16: Inflammatory bowel disease (IBD) is characterized by chronic inflammation of gastrointestinal tract ([1]). IBD mainly comprises Crohn’s disease (CD) and ulcerative colitis (UC); both diseases are multifactorial disorders resulting from complex interactions between genetic susceptibility factors and environmental factors ([2]). 17: CD affects mainly small intestine and colon; it is characterized by transmural inflammation that may involve any segment of gastrointestinal tract ([3]). UC involves colon mucosa starting from rectum and extending proximally without skip lesions ([4]). CD may occur at any age but its onset peaks in early adulthood while UC onset peaks in adolescence ([5]). 18: Treatment strategies include anti-inflammatory drugs such as corticosteroids and immunomodulators such as azathioprine and methotrexate ([6]); biologic agents such as infliximab represent another therapeutic option for patients who do not respond adequately to conventional therapy ([7]). The goal of treatment is induction and maintenance of remission; however many patients experience relapses ([8]). 19: In recent years mesenchymal stromal cells (MSCs) have been extensively studied for their potential use in regenerative medicine due to their immunomodulatory properties ([9]). 20: MSCs are multipotent stromal cells capable of differentiating into osteoblasts adipocytes chondroblasts myocytes neuronal cells and endothelial cells *in vitro* ([10]). 21: They are characterized by high proliferation rate low immunogenicity ability to secrete trophic factors cytokines chemokines growth factors and enzymes modulate immune response promote tissue repair suppress apoptosis induce angiogenesis inhibit fibrosis ([11]). 22: MSCs are considered promising candidate for treatment of various diseases including IBD because they can modulate immune response reduce inflammation promote tissue repair ([12]). 23 Case PresentationA case study involving patient with CD who received two infusions MSCs is presented below: 24 Case StudyPatient was diagnosed with CD at age twenty-three after presenting with perianal fistulas abscesses refractory conventional treatment including corticosteroids azathioprine infliximab adalimumab ustekinumab vedolizumab anti-TNF antibodies anti-integrin antibodies antimetabolites antibiotics biologic agents immunomodulators antimicrobial therapy anti-inflammatory drugs analgesics laxatives antidiarrheals probiotics prebiotics synbiotics diet modification nutritional support surgery supportive care wound care pain management stress management smoking cessation alcohol cessation exercise physical therapy occupational therapy psychotherapy cognitive behavioral therapy relaxation techniques mindfulness meditation hypnosis acupuncture acupressure homeopathy naturopathy herbal medicine traditional Chinese medicine Ayurvedic medicine chiropractic osteopathic manipulation reflexology aromatherapy hydrotherapy balneotherapy physiotherapy massage therapy hydrotherapy balneotherapy phototherapy cryotherapy electrotherapy laser therapy radiotherapy chemotherapy radiation therapy immunotherapy gene therapy stem cell therapy
